Accurate estimates of cost are vital to the suc- cess of a construction project. Developing such estimates in great detail is the responsibility of the construction estimator. Usually employed by a gen- eral contractor, the construction estimator factors in everything from the price of lumber to the cost of renting a large crane for a day, the labor pay rates to insurance coverage, and expected loss of time resulting from bad weather. The resulting estimate is used as the basis for the contractor to competitively bid on the construction contract. For firms building single homes or residential developments, such an estimate is used to set the selling price of the homes. Construction estimators usually begin with a set of detailed building plans that provide dimensions and other information needed to begin the estimate. In most cases, the estimator also visits the site. This visit provides information on terrain, site access, drainage, and the availability of utilities. Next, careful analyses of material and labor requirements are done. These are called takeoffs and are entered on standard estimating forms. The estimator must identify and enter on the forms the exact quantities of each item that the contrac- tor must provide. If portions of the work (such as plumbing or electrical) are subcontracted, the esti- mator must usually analyze the bids submitted by the subcontractors. Decisions involving sequenc- ing of operations must be made, since improperly scheduled equipment, materials, or work crews may cause delays and increased costs. Allowances must be made for shipping delays, waste and damage to materials, weather problems, and so on. While most construction estimators are employed by building contractors, some work for large architec- tural or engineering firms. Estimators may also operate their own consulting businesses, providing fee-based services to contractors, government agencies, and building owners or financing organizations. Educational requirements for construction esti- mators usually consist of a degree in a field such as construction management, engineering, or archi- tecture. A strong aptitude for mathematics and pro- ficiency with computer software are also valuable assets. Many estimators also have practical expe- rience in construction work, giving them familiarity with materials, job practices, and the various spe- cialty trades. Additional on-the-job training is usually provided, since each company has its own specific way of preparing and presenting estimates. Professional certification is voluntary, but ben- eficial. Such certification is administered by two professional organizations—the Association for the Advancement of Cost Engineering and the Society of Cost Estimating and Analysis. The requirements vary, but include a number of years of professional experience and passing an examination.

The numerical values for the mesh currents that we have in the question are given as:

We first have to write the KVL

2 - 1(i₁ - i₂) + 3 - 5(i₁ - i₃) = 0

We have to expand the equation that we have above

2 - i₁ + i₂ + 3 - 5i₁ + 5i₃ = 0

take like terms

-i₁ - 5i₁  i₂ + 5i₃ = 5

=  6i₁ - i₂ - 5i₃ = 5

-1(i₂ - i₁) - 6 i₂ - 9(i₃ - i2) = 0

after expanding we would have

i₁ - 16i₂ + 9i₃ = 0------- equation 2

-5 (i3 - i1) - 3 - 9(i3 - i2) - 7i3 = 0

5i1 + 9i2 - 2i3 = 3 ------ equation 3

From the equations that we have in 1, 2 and 3, we would solve the system of equations to get

1i = 0.9892 = 0.9892 ampere

i2 = 0.1501 ampere

i3 = 0.1570 ampere

1b. (∃x)(tall(x) ∧ (∀y)(short(y) → taller(x, y)))

1c.

Proof:

Step 1:

Assume (person(s) ∧ person(t) ∧ short(s) ∧ tall(t))

Step 2:

From Step 1, we know that (person(s) ∧ person(t) ∧ short(s) ∧ tall(t)) is true.

Step 3:

Assume ¬ taller(s, t) is false, i.e. taller(s, t) is true.

Step 4:

From Step 3, taller(s, t) is true, which contradicts the assumption in (1c) that ¬ ∃s ∃t [person(s) ∧ person(t) ∧ short(s) ∧ tall(t) ∧ taller(s, t)].

Step 5:

From Step 4, it follows that ¬ taller(s, t) must be true, i.e. (person(s) ∧ person(t) ∧ short(s) ∧ tall(t)) → ¬ taller(s, t) is true.

Step 6:

Since Step 5 holds for any s and t that satisfy (person(s) ∧ person(t) ∧ short(s) ∧ tall(t)), it follows that

(∀s)(∀t)((person(s) ∧ person(t) ∧ short(s) ∧ tall(t)) → ¬ taller(s, t)) is true.

Hence, the proof is complete.

Answer:

a) Decrease

b) Decrease

c) Decrease

d) Decrease

Explanation:

Ti= 200°F ,

Te =  170°F

Area of heat exchanger = \(\pi *(2 )* 10\)  = 20π

A) when The flow rate of the cooling fluid is increased

Temperature of process stream will decrease  and this is because the tube side heat transfer coefficient will increase and this will increase the rate of heat transfer thereby decreasing the temperature of the process stream.

B) when There are 200 tubes that are 1.0-in. OD and 20.0ft long

The temperature of the process stream will decrease and this is because the heat transfer coefficient will increase likewise the heat transfer rate

C) When The number of shell passes is doubled

This will cause an increase in the overall length of the shell, an increase in velocity of constant volumetric flowrate, hence the Temperature of the process steam will decrease as well

D) When The tube material is changed to copper.

Due to the high thermal conductivity of copper when compared to steel , switching to copper will cause a decrease in the temperature of the process steam

The flowrate Q is estimated to be 10.83 m³/s, and the uncertainty is 0.64 m³/s (i.e., 5.89%).

To estimate the uncertainty in the flowrate for the measured values: Q = 128μL ΔPπD / 4.

Where ΔP = 12kN/m² ± 0.3kN/m²; D = 0.3m ± 0.01 m,

L = 150m ± 0.1m and μ = 0.001 kg/m-s (the dynamic viscosity of water).

The formula for the uncertainty of flowrate using the given parameters can be calculated as follows:

ΔQ/Q = ΔΔP/ΔP + ΔD/D + ΔL/L Since ΔP = 12kN/m² ± 0.3kN/m²,

The percentage uncertainty in ΔP is given as follows: (0.3kN/m²/12kN/m²) × 100% = 2.5%

Similarly, the percentage uncertainty for D and L can be computed as follows:

ΔD/D = (0.01m/0.3m) × 100% = 3.33%ΔL/L = (0.1m/150m) × 100% = 0.067%

The flowrate Q can be calculated as follows: Q = 128μL ΔPπD / 4Q = 128 x 0.001 x 150 x (12/4) x 3.1416 x (0.3) ⁴ = 10.83 m³/s

The uncertainty in Q can be calculated as follows:

ΔQ/Q = ΔΔP/ΔP + ΔD/D + ΔL/LΔQ/Q = 2.5% + 3.33% + 0.067%ΔQ/Q = 5.89%

Therefore, the flowrate uncertainty is ΔQ = (5.89/100) x 10.83 = 0.64 m³/s.

The volumetric flowrate formula in a horizontal pipe for laminar flow is Q = 128 μL ΔPπD / 4.

The flowrate uncertainty can be calculated using the formula, ΔQ/Q = ΔΔP/ΔP + ΔD/D + ΔL/L.

The values of ΔP, D, and L are ΔP = 12k N/m ² ± 0.3k N/m ², D = 0.3m ± 0.01 m, and L = 150m ± 0.1m,

Therefore, the flowrate Q is estimated to be 10.83 m³/s, and the uncertainty is 0.64 m³/s (i.e., 5.89%).

Note that the magnitude of the resultant active thrust on the wall is 876.69 kN.

To calculate the magnitude of the resultant active thrust on the wall, we need to use Rankine's theory of earth pressure.

Let's assume that the wall height is also 5.4 meters, and the angle of wall friction is zero.

Then, the total active thrust (Q) is given by:

Q = Ka * H * gamma * H/2

Where,

Ka = Active earth pressure coefficient

H = height of the wall

gamma = unit weight of soil

The active earth pressure coefficient can be calculated using the following formula:

Ka = (1 - sin(phi)) / (1 + sin(phi))

Where, phi = angle of shearing resistance of soil

Substituting the given values, we get:

phi = 30 degrees

H = 5.4 meters

gamma = 19.8 kN/m^3

Ka = (1 - sin(30)) / (1 + sin(30)) = 1/3

Q = Ka * H * gamma * H/2 = (1/3) * 5.4 * 19.8 * 5.4/2 = 876.69 kN

Therefore, the magnitude of the resultant active thrust on the wall is 876.69 kN.

The line of action of the resultant active thrust on the wall will be at one-third of the height of the wall from the bottom. Therefore, the line of action of the active thrust will be at a height of 1.8 meters from the bottom of the wall.

Judging the best best film:

a. The probability that out of five judges (random sample),  three are in favor of film FA is:

= 33%.

b. The demerits of classical probability are:

1. Classical probability can only be used with events that have definite numbers of possible outcomes.  

2. Classical probability can only handle events where each outcome is equally likely.

3. Classical probability is based on the assumption of linear relationship (which is not always true in real life) between the latent variable and observed scores.

Explanation:

a) Number of judges = 11

Number of judges in favor of FA film = 6

Number of judges in favor of FB film = 5

Probability of judges in favor of FA film = 6/11

Probability of judges in favor of FB film = 5/11

Random sample of judges = 5

Probability that out of five judges, three are in favor of film FA = 3/5 * 6/11

= 18/55

= 33%

b) Classical probability is the simple probability showing that each event has equal chance of happening.  It can be contrasted with empirical probability that is obtained from experiments.

The load P is equal to the force exerted by the wire, so P = F.

This problem requires a simple application of Hooke's Law.

Hooke's law states that the force exerted by a spring is proportional to its displacement, provided that the displacement is small compared to the overall size of the spring. In this case, the guy wire can be treated as a spring, and the displacement of 0.075 inches can be used to calculate the force exerted by the wire.

The equation for Hooke's law can be written as follows:

F = k * x

where:

The spring constant for a wire can be calculated using the following formula:

k = (pi / 4) * d^2 * E / L

where:

Once the spring constant has been calculated, the force exerted by the wire can be determined by plugging the value of k and the displacement x into the equation for Hooke's law:

F = k * x = (pi / 4) * d^2 * E / L * x

So, to summarize:
