Propane fuel (C3H8) at 25 C is mixed uniformly with 50 percent excess air at 350 C in a combustion chamber at atmospheric pressure. The heat transfer ratio in the combustion chamber is 200 kW. Determine the temperature of the combustion products. The volumetric flow rate of the air is 1 m3/s. (Calculate the enthalpies using thermodynamic paths and also make use of polynomials for the CPs)
