An elementary reaction A+B  C+D is to be carried out in a non-ideal CSTR which has both bypassing and a stagnant region in this reactor. The measured reactor volume is 1.0 m3 and the flow rate to the reactor is 0.1 m3/min. The reaction rate constant is 0.28 m3/kmol.min. The feed is equimolar in A and B with an entering concentration of A equal to 2.0 kmol/m3 k. Calculate the conversion that can be expected in this reactor if the model parameters of α and β were determined from a tracer test and were found to be 0.8 and 0.3 respectively.

Consider 0.8 kg of N₂ at 300 K, 1 bar contained in a rigid tank connected by a valve to another rigid tank holding 0.3 kg of CO₂ at 300 K, 1 bar. The valve is opened and gases are allowed to mix, achieving an equilibrium state at 290 K.
Determine:
(a) the volume of each tank, in m³.
(b) the final pressure, in bar.
(c) the magnitude of the heat transfer to or from the gases during the process, in kJ.
(d) the entropy change of each gas and of the overall system, in kJ/K.

1. Consider a‘‘duel’’ between two players. Let’s call these players H and D.Now,we have historical information on each because this is not their first duel. H will kill at long range with probability 0.3 and at short range with probability 0.8. D will kill at long range with probability 0.4 and at short range with probability 0.6. Let’s consider a system that awards 10 points for a kill for each player. Build a payoff matrix by computing the expected values as the payoff for each player. Solve the game.

The price elasticity of demand for ambulatory mental health services appears to be about - 0.8, and the price elasticity for general ambulatory medical services appears to be about -0.3. How much would spending increase for each type of care if copays were cut from $40 to $25? *Hint: Need to find out how much the copay decreased by in percentage and that will give you the percentage change in price to plug into your elasticity formula. (PLEASE SHOW WORK ON HOW YOU GOT THE ANSWER, THANK YOU).

Two long concentrie cylinders have diameters of 5 and 10

cm, respectively. The inside cylinder is at 900 C and the outer

cylinder is at 100-C. The inside and outside emisivities are 0.8

and 0.4, respectively. Calculate:

a) the percent reduction in heat transfer if a cylindrical radiation

shield having a diameter of 6 cm and emisivity af 0.3 is placed

between the two cylinders.

b)discuss the effect of decreasing the shield diameter on the

percent reduction in heat transfer

c)draw the network circuit

6 In the late 1930s and early 1940s, Joe Louis handily defeated a series of opponents who came to be known as the “Bum of the Month Club.” Use what you know about rank-order tournaments to explain how this came about.

Assume CAPM is correct (the market is the tangency portfolio), and all securities are priced correctly. a), b) Fill in the blanks.

c) Suppose a well known fund manager invites you to invest in a special fund that promises expected returns of 0.06, with a BETA of 0.2. How would you approach the idea?

1) Blue Ram Brewing Company currently has no debt in its capital structure, but it is considering using some debt and reducing its outstanding equity. The firm’s unlevered beta is 1.15, and its cost of equity is 11.55%. Because the firm has no debt in its capital structure, its weighted average cost of capital (WACC) also equals 11.55%. The risk-free rate of interest (rRFrRF) is 3.5%, and the market risk premium (RPMRPM) is 7%. Blue Ram’s marginal tax rate is 25%.

Blue Ram is examining how different levels of debt will affect its costs of debt and equity, as well as its WACC. The firm has collected the financial information that follows to analyze its weighted average cost of capital (WACC). Complete the following table.

F. Pierce Products Inc. is considering changing its capital structure. F. Pierce currently has no debt and no preferred stock, but it would like to add some debt to take advantage of low interest rates and the tax shield. Its investment banker has indicated that the pre-tax cost of debt under various possible capital structures would be as follows:

F. Pierce uses the CAPM to estimate its cost of common equity, r_s and at the time of the analaysis the risk-free rate is 5%, the market risk premium is 8%, and the company's tax rate is 40%. F. Pierce estimates that its beta now (which is "unlevered" because it currently has no debt) is 1.15. Based on this information, what is the firm's optimal capital structure, and what would be the weighted average cost of capital at the optimal capital structure? Do not round intermediate calculations. Round your answers to two decimal places.

A random sample of 9 automobiles of a particular model has a mean of 32 mpg and a standard deviation of 10 mpg. Assume gas mileages are normally distributed. Use this information to compute a 95% confidence interval for the mean miles per gallon obtained by all automobiles of this type.

Round your confidence interval values to the nearest whole number (Do NOT use any decimals in your answer).

The left endpoint of the confidence interval is  , and the right endpoint is  .
