A simplified single-cylinder internal combustion engine that produces 20 hp is shown in figure 4-33. It loses 40 kJ/min in radiated and conducted heat while using 0.73 kg/min of fuel-air mixture which is assumed to have an enthalpy of 2600 kJ/kg of mixture. Determine the specific enthalpy of the exhaust gases, assuming that the engine is in a steady state.
