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 10%

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 10% 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 40 kW.
Assuming complete combustion and neglecting KE and PE effects, determine the rate of heat transfer from the engine. Use the PG mixture model.
