The CEO of 'Vale of Brazil' is considering buying a new mine. The mine is forecasted to start earning $5,250,000 of revenue four years from today. Due to a recession in mining industry, and lack of employed mining workers, the production of 'Vale of Brazil' is expecting to decrease by 10.5% p.a. (which have consequent impact on revenue.) Operating costs are 25% of the annual revenue. The mine is expected to be kept for four years, which will be sold for sale price of $4,550,000 at the end of last year. Setting up the mine will cost 1.5 mil today and 2mil in the first year and the year after. 55% of the 'Vale of Brazil' is financed through debt which has a cost of 7% and shareholders require a 3.5 percent premium on creditor's earning. - Q: What is the IRR and NPV?
3 moles of liquid water at 100\deg C and 1 atm go to the vapor phase at 160\deg C and 0.5 atm. Calculate \Delta H, \ Delta S, \Delta G, and \Delta A for the process. You can consider that the vapor behaves as an ideal gas. Data for water that you might need to solve the problem: Cpm_(vap) = 9 cal/(mol K); \Delta Hm_(vap) = 9360 cal/mol; S\deg298K Cpmvap=9 cal/(molK); AHmvap=9360 cal/mol; S°298K=16.72 cal/(molK)
A hot benzene vapor stream at 500oC and 1 bar is rapidly cooled by mixing with liquid benzene at 25oC and 1 bar. The stream leaving the mixer must be 200oC and 1 bar. Assume the reactor is at constant volume. Determine the flow rate (in mol/hr) of the liquid benzene feed stream assuming the flow rate of the hot benzene vapor stream is fixed at a certain value x (specified in the quiz question). Use the polynomial approximations for heat capacity and Table B.20 when appropriate. Assume the flow rate of the hot benzene vapor stream is fixed at 1,253 mol/hr and the liquid benzene feed stream is your reference state. What flow rate (mol/hr) of the liquid benzene feed stream must be used? Round your answer to the nearest tenth and do not include units. Use Tables B.17 and B.20 to tabulate relevant data. Remember that temperatures for polynomial heat capacities are in Kelvin.

A Schedule Builder Check #t A chemical engineer must calculate the maximum safe operating temperature of a high-pressure gas reaction vessel. The vessel is a stainless-steel cylinder that measures 48.0 cm wide and 57.6 cm high. The maximum safe pressure inside the vessel has been measured to be 6.90 MPa. 3 For a certain reaction the vessel may contain up to 7.89 kg of boron trifluoride gas. Calculate the maximum safe operating temperature the engineer should recommend for this reaction. Write your answer in degrees Celsius. Round your answer to 3 significant digits.
