Liquid octane enters an internal combustion engine operating at steady state with a mass flow rate of 0.0018 kg/s and is mixed with the theoretical amount of air. The fuel and air enter the engine at 25oC, 100 kPa. The mixture burns completely and the products leave the engine at 600oC. The engine develops a power output of 30 horsepower. Neglecting KE and PE, determine
The rate of heat transfer from the engine.
