An area can be irrigated by pumping water from a nearby river. Two competing installations are being considered. The MARR is 12% per year and electric power for the pumps costs $0.06 per kWh. Recall that 1 horsepower (hp) equals 0.746 kilowatts. (11.2, 11.3) a. At what level of operation (hours per year) would you be indifferent between the two pumping systems? If the pumping system is expected to operate 2,000 hours per year, which system should be recommended? b. Perform a sensitivity analysis on the efficiency of Pump A. Over what range of pumping efficiency is Pump A preferred to Pump B? Assume 2,000 hours of operation per year, and draw a graph to illustrate your answe

An integrated, combined cycle power plant produces 285 MW of electricity by gasifying coal. The capital investment for the plant is $450 million, spread evenly over two years. The operating life of the plant is expected to be 18 years. Additionally, the plant will operate at full capacity 76% of the time (downtime is 24% of any given year). The MARR is 10% per year. a. If this plant will make a profit of two cents per kilowatt-hour of electricity sold to the power grid, what is the simple payback period of the plant? Is it a low-risk venture? b. What is the IRR for the plant? Is it profitable? a. The simple payback period of the plant is years. (Round up to one decimal place.) It's a venture. b. The IRR for the plant is%. (Round to one decimal place.) The plant is

A steam generation system at a biomass-fueled power plant uses an electrostaticprecipitator (ESP) to clean its gaseous effluents. The power plant has consistently made use ofthe same type of ESP over the past several years. The installed cost of a new ESP has beenrelatively constant at $100,000. Records of operation and maintenance expenses indicate thefollowing average expenses per year as a function of the age of the ESP. The MVs of the ESP arealso reasonably well known as a function of age.  Data graph in image attached. Determine the best time to replace the ESP if the MARR is 15% per year.

An integrated, combined cycle power plant produces 280 MW of electricity by gasifying coal. The capital investment for the plant is $690 million, spread evenly over two years. The operating life of the plant is expected to be 17 years. Additionally, the plant will operate at full capacity 78% of the time (downtime is 22% of any given year). The MARR is 5% per year. a. If this plant will make a profit of three cents per kilowatt-hour of electricity sold to the power grid, what is the simple payback period of the plant? Is it a low-risk venture? b. What is the IRR for the plant? Is it profitable? O
