Problem $7\mathrm{.}1$

It is proposed to set up a nitric acid plant based on Ostwald Process. The expected revenues and operating expenses in millions of dollars are presented below. The fixed capital investment for the plant is $$50$ million with a working capital of $$7\mathrm{.}5$ million. Assume that all investments are made at time zero. Also, the present worth factor for cash flow in a year is $(1+i)\%$ Using MACRS depreciation schedule with a class life of $5$ years, determine

d$.$ The annual cash flows for all years

e$.$ Net present worth using nominal discount rate of $15\%$ for all years

f$.$ The DCFR
