Propane is fed to a combustion chamber at 25°C with pure oxygen. The products exit the reactor as gases, except the water, which is a liquid at 88°C. Assume a constant heat capacity of CO2 equal to 37.35 J/mol-K. If the propane is fed at 200 mole/s, determine the flow rate of O2 entering the reactor in SLPM if the reactor is adiabatic

Liquid propane (C_3H_8) enters a steady-flow combustion chamber at 25 Degree C, and 6 atm at a rate of 0.8 kg/min. It is burned with 150 percent excess air that is compressed and preheated to 400 K and 6 atm before entering the combustion chamber. The products of the combustion enter a gas turbine at 1200 K and 6 tam and leave at 700 K and 1 atm. The adiabatic efficiency of the turbine is 80%. The combustion process is...

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...

Nitric oxide and oxygen at 700°C are fed in stoichiometric ratios to a continuous flow adiabatic reactor to produce nitrogen dioxide [2NO(8)+0,(8)——2N02 (8)]. If a 70% conversion is achieved, calculate the outlet temperature. For simplicity, use the following heat capacities: NO: 37.7 J/mol-°C; NO2: 75.7 J/mol-°C; 02: 35.7 J/mol-°C.
