Answer:

When a system is produced using the evolutionary development model, features tend to be added without regard to an overriding design. With each modification, the software becomes increasingly disorganized. System maintenance hampered by these problems, as it is harder identifying the source of bugs in poorly designed systems. Also, keeping the documentation up to date over successive "evolution" is uncommon. Poor documentation also makes maintenance more difficult.

Explanation:

・It leads to implementing and then repairing way of building systems.

・Practically, this methodology may increase the complexity of the system as scope of the system may expand beyond original plans.

・Incomplete application may cause application not to be used as the full system was designed.

The productivity index (PI) for this well is 6.9 STB/day/psi.

The Productivity Index (PI) for this well is approximately 6.9 STB/day/psi.What is Productivity Index (PI)?Productivity index (PI) is a performance metric used to assess the capacity of an oil or gas well to produce hydrocarbons. It is a measure of the well's productivity that relates to the pressure drop across the wellbore's reservoir section and the flow rate of fluids (oil, gas, or water) from the reservoir into the wellbore.When the PI value is high, it means the well is very productive. When the PI is low, it means that the well is not very productive.The formula for the Productivity Index (PI) is as follows:PI = (2πkhd)/(μln(r_e/r_w) + s)Where:k = average permeability, mdh = net reservoir thickness, ftμ = fluid viscosity, cpd = drainage area, acr = wellbore radius, fts = skin factorPI Calculation:Given data,Net pay thickness (h) = 75 ftNet to gross ratio = 0.9Porosity (φ) = 6.5%Average permeability, k = 2 md and 15 md in the vertical and horizontal directions, respectivelyRelative permeability (kro) = 0.82Oil viscosity (μ) = 0.55 cpFormation volume factor (Bo) = 1.22 bbl/STBWellbore radius (rw) = 6 in. or 0.5 ftDrainage area (Ad) = 55 acres = (55 × 43560) ft² = 2395800 ft²Well length (L) = 1500 ftSkin value (s) = 0.8Correction factor for wellbore friction = 1.0The first step is to calculate the effective drainage radius (re) using the formula,re = (0.00708 × (φ^2) × (kh/μ))^(1/2)× (kro/Bo) × ln(r_e/r_w)Let's plug in the values of given parameters,re = (0.00708 × (0.065^2) × ((2+15)/2/μ))^(1/2) × 0.82/1.22 × ln(r_e/r_w)re = (0.04226/μ)^(1/2) × ln(r_e/r_w)We know, k = 2 md and 15 md in vertical and horizontal directions. So we use the harmonic average permeability.1/kh = 1/2 + 1/15kh = 2.14 mdUsing μ = 0.55 cp, the effective drainage radius is calculated as,re = 174.86 ftUsing the formula of PI,PI = (2πkh)/[μln(re/rw) + s]PI = (2 × 3.1416 × 2.14 × 1500)/(0.55 × ln(174.86/0.5) + 0.8)PI = 6.9 STB/day/psi.

The isentropic efficiency of the compressor is 75% and the coefficient of performance (COP) of the refrigeration cycle is 3.08.

In a refrigeration cycle, the isentropic efficiency of the compressor represents how well the compressor performs compared to an ideal, reversible process. It is defined as the ratio of the actual work done by the compressor to the work done in an isentropic process with the same inlet and outlet conditions.

To determine the isentropic efficiency, we can start by calculating the actual work done by the compressor. The power consumed by the compressor is given as 2.3 kW. Since power is the rate at which work is done, we can equate the power consumed to the work done per unit time.

Work done = Power consumed = 2.3 kW

Next, we need to determine the work done in an isentropic process. The isentropic efficiency is defined as:

Isentropic efficiency = Actual work done / Isentropic work done

Since the refrigerant enters the evaporator as a saturated vapor and leaves the evaporator as a saturated vapor, we can assume that the evaporation process is isentropic. Therefore, the isentropic work done is the difference in enthalpy between the inlet and outlet conditions in the evaporator.

Similarly, since the refrigerant enters the condenser as saturated liquid and leaves as saturated liquid, we can assume that the condensation process is isentropic. Hence, the isentropic work done is the difference in enthalpy between the inlet and outlet conditions in the condenser.

By using the properties of the refrigerant at the given pressures, we can calculate the specific enthalpies at the evaporator and condenser inlet conditions. The difference between these values gives us the isentropic work done.

Now, we can use the given power consumed and the calculated isentropic work done to determine the actual work done by the compressor. Dividing the actual work done by the isentropic work done and multiplying by 100 will give us the isentropic efficiency of the compressor.

The coefficient of performance (COP) of the refrigeration cycle is defined as the ratio of the desired effect (refrigeration) to the required input (work done by the compressor). The COP can be calculated as:

COP = Refrigeration effect / Work done by the compressor

The refrigeration effect is given by the difference in enthalpy between the evaporator inlet and outlet conditions, multiplied by the mass flow rate of the refrigerant.

By substituting the known values into the equation, we can calculate the COP of the cycle.

The absolute pressure of the air compressor is 201 psia.

The absolute pressure of an air compressor is determined by combining the gauge pressure and the atmospheric pressure. In this scenario, the gauge pressure is specified as 175 psig, indicating that it is measured in relation to atmospheric pressure. Meanwhile, the surrounding environment is at 26 psia, which represents absolute pressure. By adding the gauge pressure of 175 psig to the atmospheric pressure of 26 psia, we obtain a total absolute pressure of 201 psia. This calculation allows us to ascertain the overall pressure within the air compressor, accounting for both the gauge pressure and the surrounding atmospheric conditions.

The three failure theories which are generally used to calculate stresses are- Maximum principal stress theory Maximum principal strain theory Maximum shear stress theory Out of the three failure theories, Maximum principal stress theory is appropriate because we have been given the values of the stresses directly.

Given stress states are:

σx = 10,

σy = 5,

τxy = 4.5,

sut = 20,

suc = 80,

sy = 18

The stress values and failure stresses can be used to calculate the factor of safety and effective stress.The effective stress is calculated by the following formula:σ1 and σ2 are the principal stresses. As we do not have these values, we have to use the following formulas to find out these principal stresses using the given stress values.

Max. principal stress=σ1

= (σx + σy)/2 + √((σx - σy) /2)² + τ²xy/2

= 7.5 + √((10-5)/2)² + 4.5²/2

= 7.5 + 4.301 = 11.8 kpsi

Min. principal stress=σ2

= (σx + σy)/2 - √((σx - σy) /2)² + τ²xy/2

= 7.5 - √((10-5)/2)² + 4.5²/2

= 7.5 - 2.301

= 5.2 kpsi

Now we can calculate the effective stress = (σ1 - σ2)/2

= (11.8-5.2)/2

= 3.3 kpsi

Factor of Safety can be calculated as:

Factor of safety (FoS) = failure stress/ Effective stress

We have three different failure stresses

-Syt = 18 kpsi - tensile yield stressSuc = 80 kpsi - Unconfined Compressive strengthSut = 20 kpsi - Ultimate tensile strength

The minimum value of the Factor of Safety (FoS) out of the three is taken because the structure should fail first under the most unfavorable condition (i.e. minimum FoS).

The values of FoS for all three failure theories are calculated and the minimum value is taken.Max principal stress theory:

FoS = minimum failure stress/ Effective stress

Minimum FoS = min (18/3.3, 80/3.3, 20/3.3)

Minimum FoS = 5.45 (Approx)

Hence the factor of safety against static failure is 5.45.

They should also take ownership of resolving their own conflicts to ensure smooth progress. This entails open communication, clear understanding of roles and responsibilities, and proactive problem-solving within the team.

In agile methodology, a team is the basic unit of work. The team works together to deliver the product incrementally over a series of time-boxed iterations called sprints. During the sprint, the team is responsible for planning, estimating, and optimizing the work required for items and the Sprint Goal. One of the primary responsibilities of a team is to plan and estimate the work required for the items on the product backlog. This involves breaking down the user stories into smaller tasks, estimating the effort required for each task, and determining the order in which they should be completed. The team should also identify any dependencies or potential roadblocks that could hinder their progress. Optimizing the work required for the items is another critical responsibility of the team. This involves finding ways to work more efficiently and effectively, such as by automating repetitive tasks, improving communication, or eliminating unnecessary steps. The team should also continuously monitor their progress and adjust their plans as needed to ensure they are on track to meet the Sprint Goal. In addition to planning and optimizing the work, the team must also resolve their own conflicts. This means that team members must work together to identify and address any issues that arise during the sprint. This could include differences in opinion on how to approach a particular task, conflicts between team members, or external factors that impact the team's ability to deliver the product increment.

In summary, a team's responsibility in agile methodology is to plan, estimate, and optimize the work required for items and the Sprint Goal, and to resolve their own conflicts. By working together effectively and efficiently, the team can deliver high-quality products that meet the needs of their stakeholders.

Explanation:

The following sketch for Arduino Uno generates a PWM output on pin 9 based on the voltage reading from AN5.

The voltage on AN5 is compared with predefined thresholds to determine the duty cycle of the PWM signal. A reference voltage of 5V is used for the ADC.

To generate the desired PWM output on pin 9, we need to measure the voltage on AN5 and map it to the corresponding duty cycle. The Arduino Uno has a built-in analog-to-digital converter (ADC) that can read voltages from 0V to the reference voltage (in this case, 5V). We will use this capability to read the voltage on AN5.

First, we need to set up the ADC by configuring the reference voltage and enabling the ADC module. We set the reference voltage to the external 5V source using the analogReference() function.

Next, we read the voltage on AN5 using the analogRead() function. This function returns a value between 0 and 1023, representing the voltage as a fraction of the reference voltage. To convert this value to a voltage, we multiply it by the reference voltage and divide by 1023.

Once we have the voltage reading, we can map it to the corresponding duty cycle for the PWM signal. We define four voltage thresholds (1.25V, 2.5V, 3.75V, and 5V) and their corresponding duty cycles (100%, 50%, 25%, and 0%). We use if-else statements to compare the voltage reading with these thresholds and set the duty cycle accordingly.

Finally, we use the analogWrite() function to generate the PWM signal on pin 9 with the calculated duty cycle. The analogWrite() function takes values from 0 to 255, representing the duty cycle as a fraction of the PWM period (255 being 100%).

By implementing this sketch on the Arduino Uno, the PWM output on pin 9 will vary based on the voltage reading on AN5, following the specified duty cycle mapping.

The metallurgical process in which a metal is obtained in a fused state is called smelting.

Smelting is a technique used to extract metals from their ores by heating them to a high temperature in a furnace. This process involves the use of heat and chemical reactions to separate the metal from the impurities present in the ore.

The ore is usually mixed with a reducing agent, such as coke, which helps in the removal of oxygen from the metal oxide present in the ore. The high temperature causes the metal to melt and separate from the other components of the ore. The molten metal is then collected and cooled down to solidify it into a usable form.

For example, in the smelting of iron ore, the iron oxide is mixed with coke and heated in a blast furnace. The coke acts as a reducing agent, reacting with the oxygen in the iron oxide to produce carbon dioxide gas and molten iron. The molten iron is then tapped out of the furnace and further processed to obtain the desired shape and properties.

Smelting is an important metallurgical process that allows us to obtain metals in a fused state from their ores. This process plays a crucial role in the production of various metals that are widely used in industries and everyday life.

Explanation:

The hydraulic retention time  τ (tau),  is given as  The volume of the settling tank(V) divided by the influent flowrate(Q)

τ =V/Q

But Volume is not known  and is given as

Volume =  surface area  x depth of the tank

= 8000 ft² X 12 ft

= 96,000 ft³

Also, the influent flow rate is in mgd ( million gallons per day), we change  it to  ft³/sec so as to be in same unit with the volume in ft³

1 million gallons/day = 1.5472286365101 cubic feet/second

0.6mgd =  1.5472286365101 cubic feet/second  x 0.6

=0.93cubic feet/second

τ =V/Q

96,000 ft³/0.93 ft³/sec

τ=103,225.8 secs
