A gaseous fuel mixture that is 40 percent propane (C3H8) and 60 percent methane (CH4) by volume

Question:

A gaseous fuel mixture that is 40 percent propane (C3H8) and 60 percent methane (CH4) by volume is mixed with the theoretical amount of dry air and burned in a steady-flow, constant pressure process at 100 kPa. Both the fuel and air enter the combustion chamber at 298 K and undergo a complete combustion process. The products leave the combustion chamber at 423 K. Determine
(a) The balanced combustion equation
(b) The amount of water vapor condensed from the products
(c) The required air flow rate, in kg/h, when the combustion process produces a heat transfer output of 140,000kJ/h.
