A 650 bhp Diesel Engine with 6 cylinders has a brake thermal efficiency of 36 % and a jacket water loss of 27%. It uses a closed cooling system with a cooling tower 10 meters high. The temperature rise after passing the water jacket is 12 °C and the cooling tower range is 5 °C. Make a sketch showing the vital parts of the cooling tower system and calculate: a) capacity of the jacket water pump in GPM b) exhaust loss if the friction, radiation and other losses total 8%. c) cooling water flow rate in the cooling tower in liter/hr
