An internal combustion engine uses propane as a fuel. The propane and air enter the engine at 298 K, and the propane mass flowrate is 0.01 kg/s. The combustion is rich with = 1.11, so there is CO and H₂ in the exhaust, which exists at 1000 K. The heat loss from the engine to the cooling water is 120 kW. What is the power output (kW) and specific fuel consumption (sfc) of the engine?
