1.f) Methane gas (CH4) enters a combustion chamber at a rate of 3 kg/sec at a temperature of 25 °C. A 200% theoretical air is supplied at a temperature of 400K. At the middle of methane combustion process (i.e., after 50% of methane gas is burnt), liquid propane (C3H8) at 25°C is injected at a rate that produces neither CO nor O2 in the flue gases. Assume steady state and adiabatic process at 1 atm, calculate the following i. The...
