For the following two projects, determine the

1. Payback Period
2. Discounted Payback
3. Net Present Value
4. Profitability Index (Benefit-Cost Ratio)
5. Internal Rate of Return
6. Modified Internal Rate of Return

The firm’s cost of capital k_o is 15% and the risk free rate R_f is 10%. The firm assesses risk and assigns a risk index to determine a risk adjusted discount rate. An index of 1.0 would be assigned to an average risk project.

To determine risk adjusted rates the firm uses the following equation:

Risk Adjusted Rate (RADR) = R_f + [Risk Index (k_o – R_f)

Task: Rank the projects in accordance with each method of analysis.

Question 2. Consider the market for burritos in Vancouver, blessed with thousands of students and dozens of small burritos stands. The demand and supply schedules are shown in the table.

Answer:

Make a table listing the volume of milk power sample solution and the volume of BSA solution you will spike the sample with and the volume of water you will need to dilute to the final volume. The protein content of the dry milk powder is about 30%.

The available stock solutions are 1 mg/ml milk power solution, and 2 mg/ml standard BSA solution.

0, 20, 50, 100, 200, 500μg/mL standard BSA solutions are prepared in clean test tubes, by making dilutions to the original BSA solution (2 mg/mL) with water to a final volume of 600μL.

How do you do the calculations, if there are any. I want to know how. Thank you very much.

all of the concentrations should be withinthe linear range (0.01-1.0 mg/mL for protein analysis) and for accurate determination of the slope and intercept, the maximum amountof solute added from the standard should not be too high or too low (100% to 300% of the solute in the sample would be appropriate)

1. You mix 5.0 M A with 7.5 M B and allow the mixture to come to equilibrium. At equilibrium you determine there is 1.0 M A. What is the equilibrium constant? Construct an ICE table to aid you.(2 points)

                  2A(g) + B(g) ⇆ C(g) + D(g)

2. The value of the equilibrium constant is 50 for the reaction below. Which of the following set of concentration would be an equilibrium position? Explain your reasoning for each answer. (2 points)

                  A(g) + B(g) ⇆ C(g)

A. [A] = 5 M, [B] = 10 M, [C] = 50 M

B. [A] = .1 M, [B] = 20 M, [C] = 100 M

C. [A] = 1 M, [B] = 0.5 M, [C] = 25 M

D. [A] = 50 M, [B] = 50 M, [C] = 50 M

3. If Q is equal to 0, and K is equal to 0.10, explain how the following reaction will proceed. (1 point)

                  A(g) + B(g) ⇆ 2C(g)

CO₂ can be injected into an artificial aquarium, and lower the alkalinity of the environment, which is related to global warming.

CO₂  can be made using the following chemical reaction: CaCO₃ (s) + 2HCl (aq) <--> CaCl₂ (aq) + H₂O (l) + CO₂ (g).

The CO₂ will then be injected into an artificial aquarium, reacting with H₂O and CO₃^2- to create hydrogen ions and bicarbonate:

CO₂ (g) + H₂O (l) + CO₃^2- <---> H⁺ + HCO₃^-

How does one know the amounts of each chemical needed to raise the level CO₂ in 3 of 1.0 liter jars in the following quantities:

a) 450 ppm

b) 750 ppm

c) 1250 ppm.

Please can you explain the method, using pH = -log [H⁺] and P₁V₁ = P ₂V₂

The temperature of the room will be 298K and the pressure will be 1 atm [i think, since I'm only injecting the CO₂ start into the tank]. Also, how does Boyle and Henry's Law relate, I haven't the faintest clue where to start.

Thanks!

Electrical power is to be produced from a steam turbine connected to a nuclear reactor. Steam is obtained from the ractor at 540 K and 36 bar, the turbine exit pressure is 1.0 bar, and the turbine is adiabatic.

a) Compute the maximum work per kilogram of steam that can be obtained from the turbine.

A clever chemical engineer has suggested that the single-stage turbine considered here be replaced by a two-stage adiabatic turbine, and that the steam exiting from the first stage be returned to the reactor and reheated, at constant pressure, to 540 K, and then fed to the second stage of the turbine.

b) Compute the maximum work obtained per kilogram of steam if the two-stage turbine is used and the exhaust pressure of the first stage is 0.5(36 + 1) = 18.5 bar.

c) Compute the maximum work obtained per kilogram of steam if the two-stage turbine is used and the exhaust pressure of the first stage is sqrt(36 x 1) = 6 bar.

d) Compute the heat absorbed per kilogram of steam in the reheating steps

In CPM, what is the completion time of the project?

Tower Engineering Corporation is considering undertaking several proposed projects for the next fiscal year. The projects, the number of engineers and the number of support personnel required for each project, and the expected profits for each project are summarized in the following table: Project 1 2 3 4 5 6 Engineers Required 20 55 47 38 90 63 Support Personnel Required 15 45 50 40 70 70 Profit ($1,000,000s) 1.0 1.8 2.0 1.5 3.6 2.2 Formulate an integer program that maximizes Tower's profit subject to the following management constraints: 1) Use no more than 175 engineers 2) Use no more than 150 support personnel 3) If either project 6 or project 4 is done, both must be done 4) Project 2 can be done only if project 1 is done 5) If project 5 is done, project 3 must not be done and vice versa 6) No more than three projects are to be done.

A 90 kg man stands in a very strong wind moving at 12 m/s at torso height. As you know, he will need to lean in to the wind, and we can model the situation to see why. Assume that the man has a mass of 90 kg, with a center of gravity 1.0 m above the ground. The action of the wind on his torso, which we approximate as a cylinder 50 cm wide and 90 cm long centered 1.2 m above the ground, produces a force that tries to tip him over backward. To keep from falling over, he must lean forward.

A. What is the magnitude of the torque provided by the wind force? Take the pivot point at his feet. Assume that he is standing vertically. Assume that the air is at standard temperature and pressure. Express your answer with the appropriate units.

B. At what angle to the vertical must the man lean to provide a gravitational torque that is equal to this torque due to the wind force? Express your answer in degrees.
