Cash Flow Worksheet HW ChEE 442 Due 10/2 Done individually Problem statement: The balance sheet for a proposed project reveals a fixed capital investment of $350M. Annual total project expenses are estimated to be $150M and sales income as $240M. Calculate annual and cumulative cash flows for an estimated project lifetime of 10 years. Assume the plant is constructed in 3 years with $100M invested the first and second years and $150M in the third. Sales income in year 4 is only 2/3 normal. Working capital is $50M. Assume straight line depreciation with zero scrap value. Interest rate is 20% Activities: Create cash flow worksheet for this problem (in excel) including NPV assuming ROR of 20% 1.
