4. A diesel engine with the following specifications, 12 cylinders, 0.75 m x 0.95 m, four stroke cycle has a fuel consumption 0.75 kg/kW-hr based on 15,500 kJ/kg. Engine speed is 375 rpm with an indicated mean effective pressure of 20.5 bar. If the jacket water carries away an estimated 32% of the heat supplied, find its capacity in cubic meter per second required if the allowable rise is 150°C.
