The required ventilation rate is 400 cfm.

H = height office = 10 feet

W = width office = 20 feet

L = length office = 20 feet

ACPH = air change per hour = 6

Basically the formula to calculate the required ventilation rate is by multiply the ACPH with the space volume.

We know the office space have block shape with volume formula is H*W*L. So the required ventilation rate is,

Required ventilation rate = 6 * (10 * 20 * 20)

= 24,000 cubic feet per hour

Since the question want the result in cfm or cubic feet per minute, so we divide the result by 60 to convert that to cfm. So,

CFM = 24,000 / 60

= 400 cfm

Thus, the required ventilation rate in cfm is 400.

Answer: it spread by winds has a strong effect on fire behavior due to the fanning effect on the fire.Wind increases the supply of oxygen.

Explanation:

Fires need three things to occur in order to start and grow: oxygen, a spark/heat, and fuel. Wildfires in forests have plenty of fuel and heat is never really an issue, therefore the wind can cause a fire to continue and even spread faster. Wind will not only increase the fire's supply of oxygen, but it will   also blow the fire in many different directions, now causing the flames to spread.

Answer: the temperature of the inner surface is 599.55 K

Explanation:

first, let Am²  represent area of the oven surface

now heat transfer rate due to convection

qconv = hAΔT

where ΔT is temperature difference in kelvin (To -Ts) temperature of outer surface - temperature of surroundings

ΔT = 400K - 300k = 100k

and h = 20 W/m².K

so we substitute

qconv = 20 × A × 100 = 2000A W

Now heat transfer due to emission

qemi = ∈α(To⁴ - Ts⁴)A

∈ is emissivity =  0.8, α is boltzman constant = 5.67×10⁻⁸ W/m⁻²K⁻⁴

so we substitute

qemi = 0.8 × 5.67×10⁻⁸ (400⁴ - 300⁴)A

qemi = 4.536×10⁻⁸ × 1.75×10¹⁰ × A

qemi =  793.8A W

NOW total heat loss rate = Qconv + Qemi

2000A + 793.8A = 2793.8A W

so since outer surface is to be maintained at a temp of 400K then heat must be transferred from inner surface to outer surface at the same rate.

Therefore

Heat transfer rate to outer surface by conduction = kA(Ti-To)/L

k is thermal conductivity  0.7 W/m.K, Ti is temperature of inner surface, L is the thickness of plate  0.05m

so Heat transfer rate = 0.7× A × ( Ti - 400 ) / 0.05

Now

This heat transfer rate equals heat loss rate

so  0.7× A × ( Ti - 400 ) / 0.05  =  2793.8 × A

divide both side by A

THEREFORE

Ti = 400 + 199.55

Ti = 599.55 K

∴  the temperature of the inner surface is 599.55 K

Answer:

Steel can rusts easily in the presence of moisture and oxygen, and tarnishes as the rust progresses.

Explanation:

Steel is an alloy of carbon and iron. it is a very useful alloy that is found in almost any engineered piece. The problem with steel is that it is very susceptible to rust, and the cost of maintaining it in order to prevent rust is very high. Steel rusts in the presence of moisture and oxygen (rust is an oxidation-reduction process). Using it as a water slide exposes it constantly to moisture, and to prevent it from rusting in this case will involve a lot of maintenance cost, which is why steel is not advisable to be used in this case.

Answer:

Steel is an inorganic material, and these are rarely efficient.

This question is not complete, the complete question is;

The stagnation chamber of a wind tunnel is connected to a high-pressure air bottle farm which is outside the laboratory building. The two are connected by a long pipe of 4-in inside diameter. If the static pressure ratio between the bottle farm and the stagnation chamber is 10, and the bottle-farm static pressure is 100 atm, how long can the pipe be without choking? Assume adiabatic, subsonic, one-dimensional flow with a friction coefficient of 0.005

Answer:

the length of the pipe is 11583 in or 965.25 ft

Explanation:

Given the data in the question;

Static pressure ratio; p1/p2 = 10

friction coefficient f = 0.005

diameter of pipe, D =4 inch

first we obtain the value from FANN0 FLOW TABLE for pressure ratio of ( p1/p2 = 10 )so

4fL\(_{max}\) / D = 57.915

we substitute

(4×0.005×L\(_{max}\)) / 4  = 57.915

0.005L\(_{max}\) = 57.915

L\(_{max}\) = 57.915 / 0.005

L\(_{max}\)  = 11583 in

Therefore, the length of the pipe is 11583 in or 965.25 ft

When we talk of cuvette,we are talking about the instrument we use to hold the solutions that we make use of in the calorimetry experiment and so we will take a measurement of the volume of the solution,if there is some water and other impurities present,we will go ahead to take a measurement of the more volume, however,if some water or other impurities are there,will go ahead and take a measurement of the more volume and now,it will be less of the actual content as a result of some amount of water or impurity in it.

When Concentration = Mass/Volume

A higher volume will be taken, then assumption of mass can be made to be the same because the water or the impurity will as well have mass and as we are taking the mass long also with the mass of the sample when doing this.

Therefore,the concentration will be less.

When the mean velocity doubles, the head loss becomes 32 m per meter of pipe length. The head loss in a laminar flow of a liquid through a pipe can be calculated using the Darcy-Weisbach equation:

Δh = f * (L/D) * (V^2/2g)

Where:

Δh is the head loss

f is the friction factor

L is the pipe length

D is the pipe diameter

V is the velocity of the fluid

g is the acceleration due to gravity

Given:

Diameter of the pipe (D) = 2.5 cm = 0.025 m

Head loss (Δh) at velocity V = 0.5 m/s = 2 m/m

Velocity (V) = 2 * 0.5 m/s = 1 m/s

To find the head loss when the mean velocity doubles, we need to calculate the new head loss (Δh') using the same pipe diameter and new velocity.

Using the Darcy-Weisbach equation, we have:

Δh = f * (L/D) * (V^2/2g)

Since the pipe diameter and length remain the same, and the acceleration due to gravity (g) is constant, we can rewrite the equation as:

Δh = f * (V^2/2g)

Now, let's calculate the new head loss (Δh') at the doubled mean velocity:

Δh' = f * (V'^2/2g)

Where V' = 2 m/s (doubled mean velocity)

To find the relationship between Δh and Δh', we can use the following equation:

Δh / Δh' = (V^2 / V'^2)

Plugging in the given values:

2 m/m / Δh' = (0.5 m/s)^2 / (2 m/s)^2

2 m/m / Δh' = 0.25 / 4

2 m/m / Δh' = 0.0625

Now, rearranging the equation to solve for Δh':

Δh' = 2 m/m / 0.0625

Δh' = 32 m/m

Therefore, when the mean velocity doubles, the head loss becomes 32 m per meter of pipe length.

As a project manager, I would employ the following strategy to address resistance to changes in the home renovation project:

Strategy: Effective Communication and Stakeholder Engagement

To address resistance to changes, it is crucial to establish open and transparent communication channels with all stakeholders involved in the project. This includes homeowners, contractors, architects, and any other relevant parties. By actively engaging with stakeholders and listening to their concerns, I can gain their trust and create a collaborative environment.

Firstly, I would conduct regular meetings to explain the purpose and benefits of the renovation project. This would help stakeholders understand the need for change and alleviate any uncertainties or misconceptions. Clear and concise communication is key to ensuring everyone is on the same page.

Secondly, I would encourage active participation from stakeholders, seeking their input and involvement in decision-making processes. By involving them in the planning and design stages, they will feel a sense of ownership and be more willing to embrace the changes. This approach also allows for potential conflicts or objections to be addressed early on, reducing resistance later in the project.

Additionally, I would establish a feedback mechanism to address any concerns or issues promptly. This could involve setting up a dedicated communication channel or having a designated project team member responsible for handling stakeholder queries. Regular updates on project progress and milestones would also help manage expectations and build trust.

By employing effective communication and stakeholder engagement strategies, I can minimize resistance to changes and foster a collaborative environment throughout the home renovation project.
