A four-cylinder, four-stroke diesel engine is used to generate an output of 200A at 210V. The generator and mechanical efficiencies are 90 % and 87%, respectively. The quantity of fuel supplied to the engine is 10 kg/h with a mass analysis of 86.2 % carbon and 13.8 % hydrogen. The molecular weight of the fuel is 167 g/mol. Assume that the products of combustion are CO2, H20 and N2 with 20 % excess air. The specific gravity of the fuel used is 0.84 and the formula for the higher heating value from the Bureau of Standard is: HHV = 22,230 - 3,780(S.G.^2) BTU/lb. The jacket cooling water for the diesel electric power plant flows at 0.25 kg/s which is first used to lower the temperature of the lubrication oil through an indirect oil cooler. The jacket cooling water enters the oil cooler at 29 C and leaves at 32 C in which it will be then used to cool the diesel engine. The jacket cooling water leaves the engine at 60 C. The exhaust gas temperature is 300 C and about 1.2 kg of steam is formed per kg of fuel. The exhaust gas is composed of steam and dry gas with specific heats of 2.1 kJ/kg-K and 1.02 kJ/kg-K, respectively. The ambient temperature is 28 C.

1. Draw the schematic diagram of the diesel-electric power plant 

2. Solve for electric power, brake power, indicated power, heat supplied, loss in jacket water, loss in oil cooler, loss in exhaust
