Question: Liquid octane (C8H18) enters an internal combustion engine operating at steady state with a mass flow rate of 0.002 kg/s and is mixed with 20%

Liquid octane (C8H18) enters an internal combustion engine operating at steady state with a mass flow rate of 0.002 kg/s and is mixed with 20% excess air. Fuel and air enter the engine at 25oC, 1 atm and the products leave the engine at 500 K. The engine develops a power output of 35 kW. Assuming complete combustion and neglecting KE and PE effects, determine the rate of heat transfer from the engine. Use the IG mixture model.
