The pressure drop in a cooling duct is an important performance factor. A circular duct with a diameter of 4 ft carrying air at 55\deg F at a flow rate of 1,000 ft per minute has a pressure drop design value of 0.1 inch of water per 100 ft of duct length. Calculate the values of the pressure coefficient and Reynolds number, which are important non-dimensional parameters in this problem.

It is assumed that this initial expenditure will be depreciated using the simplified straight-line method down to zero over 10 years. The project will also require a down payment. Finally, assume that the firm's marginal tax rate is 38 percent. a. What is the initial cash outlay associated with this project? b. What are the annual net cash flows associated with this project for years 1 through 10? c. What is the terminal cash flow in year 10? That is, what is the free cash flow in year 10 plus any additional cash flows associated with termination of the project? d. What is the project's NPV given a required rate of return of 12 percent? The initial cash outlay associated with this project is $1,430,000 (Round to the nearest dollar). The terminal cash flow in year 10 (that is, the free cash flow in year 10 plus any additional cash flows associated with termination of the project) is $247,500 (Round to the nearest dollar). Given a required rate of return of 12%, the project's NPV is $ (Round to the nearest dollar).
