A small ship designed to travel at 10 knots needs 2000-kWe propulsion power and 500 kW_e for housekeeping loads. If it is desired to redesign the power plant for a higher speed of 15 knots, determine the total: 

(1) Kilovolt-ampere rating of the new electrical generators, 

(2) Horsepower rating of the new diesel engines, and

(3) Diesel fuel consumption in U.S. gallons for a 1000-nautical-mi. round trip at 15 knots. Assume that (i) the housekeeping load remains the same, (ii) the new generators have 90% power factor and 92% efficiency, and (iii) the thermodynamic cycle efficiency of the engines is 50%.
