Consider an engine running on propane (C3Hg). Both the fuel and air enter the engine at 298 K and 100 kPa. The combustion can be assumed to be complete with an equivalence ratio of 0.8. The exhaust temperature and pressure are 1000 K and 100 kPa. Estimate the heat transfer from the engine per unit mass of propane if the work production of the engine is 20% of the LHV of the fuel.
