Liquid propane (C3H8()) enters a combustion chamber at 25oC and 1 atm at a rate of 0.4 kg/min where it is mixed and burned with 150 percent excess air that enters the combustion chamber at 25oC. The heat transfer from the combustion process is 53 kW. Write the balanced combustion equation and determine
(a) The mass flow rate of air
(b) The average molar mass (molecular weight) of the product gases
(c) The average specific heat at constant pressure of the product gases
(d) The temperature of the products of combustion.
