The following observations were made during a test on an oil engine: Brake power = 30 kW Fuel used = 10 kg/h Calorific value of fuel = 42,000 kJ/kg Jacket circulating water = 9 kg/min Rise in temperature of cooling water = 60°C The exhaust gases are passed through the exhaust gas calorimeter for determining the heat carried away by exhaust gases. Water circulated through exhaust gas calorimeter = 9.5 kg/min Rise in temperature of water passing through the calorimeter = 40°C Temperature of exhaust gases leaving the calorimeter = 80°C Air/fuel ratio on mass basis = 20 Ambient temperature = 17°C Mean specific heat of exhaust gases = 1.0 kJ/(kg K) Specific heat of water = 4.18 kJ/(kg K) Draw up a heat balance sheet on kJ/min and percentage basis.
