During test on a diesel engine the power developed by the engine is used for driving a DC generator with output of 210 ampere at 200 volt. The efficiency of generator is 82%. The fuel of 42600 kJ/kg calorific value is supplied to the engine at 11.2 kg/hr. The air fuel ratio was 18:1. The exhaust gases were passed through an exhaust gas calorimeter for which the observations were as follows:
Water circulated through at 580 liters/hr, temperature rise of water through calorimeter is equal to 36°C. Temperature of exhaust gases at exit from calorimeter is 98°C. Ambient temperature is 20°C. Heat lost to jacket cooling water is 32% of total heat supplied. If the specific heat of exhaust gases be 1.05 kJ/kgK, draw up the heat balance sheet on minute basis.
