FDG&E faces acute power peak problems during the utility peak hours. An engineer proposed to pump water to the top of a nearby hill during off-peak hours and use the stored water to run hydroelectric power to produce electricity during the peak hours. The target is to produce 50 MW. Your task is to: size the required single pump (unless such a size doesn't exist) and provide the characteristics of the pump (efficiency, rpm, ... at which the pump will operate.) Show if the pump power can be offset by the recovered hydroelectric power, Calculate the price at which the peak electricity must be sold to recover investment cost, assuming reasonable profit, 30 years of lifetime, and 5% complex interest rate to finance the project. Assume that the hill, which is 1000 ft high, has sufficient top surface area to store all the water needed for this project

An automotive engineer wants to estimate the cost of repairing a car that experiences a 40 KPH head-on collision. He crashes 24 cars, and the average repair is 11 THOUSAND dollars. The standard deviation of the 24-car sample is 2 THOUSAND dollars. Determine the margin of error (ME) for a 95% confidence interval for the true mean repair cost. O A. (10.2, 11.8) O B. 1.96 O C. 3.92 D. 0.85 The American Society for Testing and Materials standard E23 defines standard test methods for notched bar impact testing of metallic materials. The Charpy V- notch (CVN) technique measures impact energy and is often used to determine whether or not a material experiences a ductile-to-brittle transition with decreasing temperature. Ten measurements of impact energy (J) on specimens of A238 steel cut at 60 degrees Celsius are as follows: 64.1, 64.7, 64.5, 64.6, 64.5, 64.3, 64.6, 64.8, 64.2, and, 64.3. Assume that impact energy is normally distributed with o = 1 Joule. Find the 95% confidence interval for the mean impact energy. O A. [64.18, 64.88] B. [63.84, 65.08] O C. [63.94, 64.98] D.

The marketing department has come up with the estimate that Applied Nanotech can sell 16 units per year at $304,000 net cash flow per unit for the next four years. The engineering department has come up with the estimate that developing the machine will take a $14.8 million initial investment. The nance department has estimated that a discount rate of 12 percent should be used. a. What is the base-case NPV? [A negative answer should be indicated by a minus sign.
