Problem 3: Civic Waterworks Consider the historic fountain in Ferril Lake in Denver's City Park. According to Friends of the Electric Fountain, it is powered by two 125 horsepower pumps, and it can spray water up to 65 feet above the lake surface. Part A Assuming the upward jet of water has a cross-sectional area of 0.050 ft2 and the pump has an efficiency of n = 0.60, what electrical power is required to achieve the full 65 ft height? Part B Assume the fountain runs for 12 hours/day and for 3 months/year and electricity costs 10c per kilowatt-hour (kWhr). Use your result from Part A to calculate the annual electricity cost [S]. http://t
