A wastewater containing 150 mg/l chlorobenzene is treated in a laboratory adsorption unit using a PVC column, 1.0 inch internal diameter, to an effluent concentration of 15 mg/l . Service times, and throughput volumes at specified depths and flowrates associated with a breakthrough concentration of 15.0 mg/l are given in table 1.

Loading rate,gpm/ft²   Bed depth,ft Throughput volume, gal Time, hr

1) is the attainable effluent concentration satisfactory from a regulatory standpoint?

2) determine the Bohart-Adams constant ( K,N₀ and x₀) for each hydraulic loading.

3)base on data derived above design an adsorption column 2.0 ft internal diameter to treat a wastewater flow 5,000 gal/d containing 150 mg/l of CB. The attainable effluent concentration is 15 mg/l and it is desired to operate the column for 90 days(8 hourslday,7 days/week) before reching exhaustion.

4)calculate the yearly carbon requirements in cubic feet.

​(Related to Checkpoint​ 15.2)  ​(EBIT-EPS analysis)  Abe Forrester and three of his friends from college have interested a group of venture capitalists in backing their business idea. The proposed operation would consist of a series of retail outlets to distribute and service a full line of vacuum cleaners and accessories. These stores would be located in Dallas, Houston, and San Antonio. To finance the new venture two plans have been​ proposed:

Plan A is an​ all-common-equity structure in which ​$2.2 million dollars would be raised by selling 84,000 shares of common stock.

Plan B would involve issuing ​$1.2 million in​ long-term bonds with an effective interest rate of 11.8 percent plus another $ 1.0 million would be raised by selling 42,000 shares of common stock. The debt funds raised under Plan B have no fixed maturity​ date, in that this amount of financial leverage is considered a permanent part of the​ firm's capital structure.

Abe and his partners plan to use a 40 percent tax rate in their​ analysis, and they have hired you on a consulting basis to do the​ following:

a.  Find the EBIT indifference level associated with the two financing plans.

b.  Prepare a pro forma income statement for the EBIT level solved for in part a that shows that EPS will be the same regardless whether Plan A or B is chosen.

WACC and Optimal Capital Structure

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 7%, 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 0.9. 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.

The attached numberpairs.csv file contains lines of comma-separated number pairs, e.g.

2.0,1
5.5,2
10,0
5.1,9.6

• Write a program which reads the file using the Python CSV module, creates a list from the contents, then divides the first number in each line by the second.
• Define a function in your program that performs the division operations; the function must accept two numeric parameters, divide the first parameter by the second, and return the result. Before dividing, your function must validate the second parameter; if it is zero, raise a ZeroDivisionError exception which includes the string "denominator is zero!" as a parameter instead of processing the division operation. Do not display any output in your function.
• Define a second function which reads the CSV file and returns the list of number pairs.
• Your main function must call the file reader function, then process the list by calling your divide function repeatedly and displaying the results (include the contents of the raised exception object, if applicable).

Expected Output:

2.0 divided by 1.0 is 2.0
5.5 divided by 2.0 is 2.75
10.0 divided by 0.0 error: denominator is zero!
5.1 divided by 9.6 is 0.53125

What is the file name I should save this under for the CSV file to run properly I keep getting an error when trying to run the code?

2a. Write a function that outputs the amount of freezing point depression (in degrees C) given a mass of magnesium chloride salt and a volume of water. Formula to calculate freezing point depression: ΔT = iKm in which ΔT is the change in temperature in °C, i is the van't Hoff factor, which = 3 for MgCl2 because it dissociates into three ions, one Mg+2 and two Cl- , K is a constant that equals 1.86 °C kg/mol and m is the molality of the solute in mol/kg. Other useful information so you don’t have to look it up: Moles of MgCl2 = (mass MgCl2)/((atomic mass Mg)+2*(atomic mass Cl)) Atomic mass Mg = 24.31 Atomic mass Cl = 35.45 Assume the density of water is 1.0 g/mL

2b. Use your function to calculate the depression for 100g MgCl2 dissolved in 500mL water

2c. Use your function to calculate the depression for 220g MgCl2 dissolved in 1L water

2d. Make a plot that shows the mass of MgCl2 necessary to depress the freezing point of a given volume (range: 1L - 100L) water by 1 degree Celsius. Give your plot appropriate labels and a title.
