A water turbine is to be designed to produce 27MW when running at 93.7 rev/min
under a head of 16.5m. A model turbine with an output of 37.5kW is tested under
dynamically similar conditions with a head of 4.9m . Calculate the:
a. model speed; b. scale ratio; c. assuming a model efficiency of 88%, estimate the volume
flow rate through the model; and d. if it is estimated that the force on the thrust bearing of
the full-size machine is 7.0GN , determine the bearing thrust of the model.
Answers
The Answers for the given question are as follow:
a. The model speed is approximately 31.62 rev/min.
b. The scale ratio is approximately 0.0417.
c. The estimated volume flow rate through the model is approximately 943.44 m^3/s.
d. The bearing thrust of the model is approximately 9.72 kN.
To calculate the required values for the water turbine model, we can utilize the concept of dynamic similarity.
a. To find the model speed, we can use the principle of geometric similarity, which states that the ratio of speeds is equal to the ratio of the square roots of the head. Thus:
Model speed = (√(Model head))/(√(Full-size head)) * Full-size speed
= (√4.9/√16.5) * 93.7 rev/min
= 31.62 rev/min
b. The scale ratio can be determined using the equation:
Scale ratio = (√(Model power))/(√(Full-size power))
= (√37.5kW)/(√27MW)
≈ 0.0417
c. To estimate the volume flow rate through the model, we can use the power equation:
Model power = (Model efficiency) * (Volume flow rate) * (Model head) * (Gravity)
37.5kW = 0.88 * (Volume flow rate) * 4.9m * (9.81m/s^2)
Solving for the volume flow rate:
Volume flow rate = 37.5kW / (0.88 * 4.9m * 9.81m/s^2)
≈ 943.44 m^3/s
d. To calculate the bearing thrust of the model, we can use the principle of force similarity:
Bearing thrust model = (Model power / Full-size power) * Full-size bearing thrust
= (37.5kW / 27MW) * 7.0GN
≈ 9.72kN

What should be given to a customer before doing a repair?
A:An estimate of final cost
B:the new parts
C:The old parts
D:a required parts list
Answers
Before doing a repair an estimate of the final cost is given to the customer. Thus the correct option is A.
What is a Customer?
A customer is referred as an individual who purchases a product whereas a person who utilizes a product or is the end user of any product is referred to as a Consumer.
For example, when parents purchase baby food, they will be considered customers, the end user is a kid so he will be the consumer. There is no necessity that the customer will be a consumer always.
A customer is provided a final pricing estimate prior to performing a repair. Before you finalize your plans and request quotations, an estimate will offer you a general sense of the cost.
An estimate will give you a broad idea of the cost, which will help you choose the budget before you finalize your plans and get quotes. The budget aids in resolving all issues with the project's overall cost estimation.
Therefore, option A is appropriate.

The barometric sensor reads the barometric pressure (the density of the atmosphere according to altitude and weather conditions)
Answer: The BARO sensor informs the PCM about changes in weather and B.altitude
Explanation: The barometric sensor reads the barometric pressure (the density of the atmosphere according to altitude and weather conditions). The barometric pressure (BARO) sensor works in conjunction with the manifold absolute pressure (MAP) sensor to provide constant pressure difference information to the PCM. Barometric pressure is the size of air strain in the atmosphere, in particular the size of the load exerted by way of air molecules at a given point on this planet. The Manifold Absolute pressure sensor performs 'double obligation' as a barometric stress sensor as soon because the key's turned on. With the key became on (prior to the engine starting) there is no vacuum inside the engine applied to the MAP sensor therefore its sign to the ECM will become a BARO studying useful in determining air density.

Air that initially occupies 0.44 m3 at a gauge pressure of 55 kPa is expanded isothermally to a pressure of 101.3 kPa and then cooled at constant pressure until it reaches its initial volume. Compute the work done by the air. (Gauge pressure is the difference between the actual pressure and atmospheric pressure.)
Answers
The work done by air in the total process is 5.80 × 10³ J
What is work done in an isothermal process?When a gas is compressed isothermally, work is said to be done on the system to reduce volume and increase pressure.
The work done in an isothermal process is expressed by using the relation:
\(\mathbf{W = \int ^{V_f}_{V_i} pdV} \\ \\ \\ \mathbf{W = nRT \int ^{V_f}_{V_i} \dfrac{dV}{V} } \\ \\ \\ \mathbf{ W= nRt In \dfrac{V_f}{V_i}}\)
From ideal gas equation;
PV = nRT;V = nRT/PFor the initial volume and final volume, we can say:
\(\mathbf{\dfrac{V_f}{V_i }= \dfrac{P_i}{P_f}}\)
Then,
\(\mathbf{W = P_i V_i In \dfrac{P_i}{P_f}}\)
where;
P_i = initial pressureV_i = initial pressure\(\mathbf{P_i= }\) 0.55 × 10⁵ Pa + 1.013 × 10⁵ Pa
\(\mathbf{P_i= }\) 1.563 × 10⁵ Pa
\(\mathbf{W = 1.563 \times 10^5 (0.44 ) In (\dfrac{1.563 \times 10^5 }{1.013 \times 10^5})}\)
W = 3.00 × 10⁴ J
When there is constant pressure during the process, the work done by the gas is:
\(\mathbf{W = P_f(V_i - V_f)}\)
where;
\(\mathbf{V_f = (\dfrac{P_i V_i}{P_f})}\)
Thus;
\(\mathbf{W = P_f(V_i - \dfrac{P_i V_i}{P_f})}\)
\(\mathbf{W = ( P_f -P_t)V_i}\)
\(\mathbf{W = (1.013 \times 10^5 \ Pa - 1.563 \times 10^5 Pa)(0.44 \ m^3)}\)
W = -2.42 × 10⁴ J.
Finally, the total work done by the air in the total process is:
W = 3.00 × 10⁴ J - 2.42 × 10⁴ J
W = 5.80 × 10³ J

The width of a strand of fiber is 19.2 micrometers. If 1000 strands are adhered side by side, how wide would the resulting fabric be if measured in centimeters?
Answers
Answer:
Explanation:
To find the width of the resulting fabric in centimeters, we need to first convert the width of a single strand from micrometers to centimeters.
1 micrometer (um) = 0.0001 cm.
So, the width of a single strand of fiber is:
19.2 um * 0.0001 cm/um = 0.00192 cm
If 1000 strands are adhered side by side, the width of the resulting fabric would be:
1000 * 0.00192 cm = 1.92 cm
So the width of the resulting fabric if 1000 strands are adhered side by side would be 1.92cm

The electric drive system in a hybrid vehicle is being discussed. Technician A says the electric drive system increases the speed of the internal combustion system increases the speed of the internal combustion up to 2,500 rpm whenever the vehicle is stopped and idling. Technician B says the regenerative braking system adds mechanical stress and intensifies part wear of the conventional friction brake pads and brake rotors. Who is right?
Answers
The statement made by Technician A is inaccurate. The hybrid car's electric propulsion system does not boost the idle speed of the internal combustion engine.
Why is Technician A incorrect?Rather than idling the engine, the electric motor is usually able to supply power when the vehicle is at a standstill or moving at a slow pace, thus resulting in reduced or eliminated engine idle needs.
The accuracy of Technician B's statement is somewhat accurate. Hybrid cars' regenerative braking systems efficiently accumulate the energy released during deceleration, converting it into electrical energy and storing it in the battery.
The system's responsibility of reducing the vehicle's speed can actually diminish the wear on usual brake components, rather than intensifying it. The reason for this is that the vehicle requires lower levels of friction when the regenerative braking is actively assisting in decelerating.
Both Technician A and Technician B are partly erroneous in their assertions.

How much will it cost to train the entire company to use a recycling program if the training includes paper handouts? (Remember, the training will take one hour and a team of three people will take three hours each to create the training program.) With the current budget, is it possible to train the company and buy recycling carts if recycling pickup in your city is free? Assume the best choice for recycle carts in your area was $80 per cart.
Answers
Answer:
With the current budget of $1,000, it is possible to train the company and buy 3 recycling carts given that recycling pickup within the area is free
Explanation:
The office waste management budget that is not being spent = $1,000
The given expense parameters are;
The training cost per hour per employee = $12.00
The number of people in the entire company = 45
The cost of preparing the training material per hour = $20.00
The number of people to create the training material = 3 people
The time it will take each person in creating the training material = 3 hours
The cost of recycling cart = $80.00 per cart
The cost of paper handouts per employee = $0.05
The cost of materials include;
The total cost for the training = $12.00 × 45 = $540
The cost for the handout = $0.05 × 45 = $2.25
The cost of preparing the materials = $20.00 × 3 × 3 = $180.00
The total costs of the training = $540 + $4 + $180.00 = $724
The amount available to buy cart = $1,000 - $724 = $276
Therefore;
The amount available to buy cart = $276
The number of carts that can be bought = 276/80 = 3.45 carts
Therefore, we round down to get;
The number of carts that can be bought = 3 carts

a) A suspended floor is a ground floor with a void underneath the structure. The floor can be formed in various ways, using timber joists, precast concrete panels, block and beam system or cast in-situ with reinforced concrete. However, the floor structure is supported by external and internal walls.
b) Soil exploration consists of determining the profile of the natural soil deposits at the site, taking the soil samples and determining the engineering properties of soils using laboratory tests as well as in-situ testing methods
c) Bulking in sand Occurs When dry sand interacts with the atmospheric moisture. Presence of moisture content forms a thin layer around sand particles. This layer generates the force which makes particles to move aside to each other. This results in the increase of the volume of sand.
d) In a nutshell, bearing capacity is the capacity of soil to support the loads that are applied to the ground above. It depends primarily on the type of soil, its shear strength and its density. It also depends on the depth of embedment of the load – the deeper it is founded, the greater the bearing capacity.
