8. (10%) Two pumps are being considered for service in Africa. Each can draw water from a depth of 50 meters and both pumps deliver 60 horsepower (output) to the pumping operation. One of the pumps must be selected. It is expected that the pump will be in use 800 hours per year and electricity costs $0.14 per kilowatt-hour. The following data are available. Recall that 1hp=0.746kW. The MARR is 15% per year. Determine which alternative should be selected if the repeatability assumption applies
