The engine develops brake power of 400 kW and consumes 1 liter of fuel in 30 sec (having a heating value of 44000 kJ/kg and density of 0.85 gm/cm3) that uses air of density 1.16 kg/m3 at ambient conditions of pressure and temperature of 1 bar and 27°C. For cooling water flow rate of 9 Kg/sec with temperature rise of 10 °c, pressure drop across air box orifice of 10 cm Hg for orifice diameter of 10 cm with discharge coefficient of 0.61 and exhaust gases temperature of 447 °c, Provide the engine heat balance showing the percentage of un-account power due to heat loss.
