calculation of mass flow rate of Exaust gas

[shoaibjamil]

I want to calculation of mass flow rate of Exaust gas from gas engine. i have fuel (gas) consumption available. please someone guide me how to proceed further. thanks in advance

Do you have engine data?

bmep=2xbrake power/(total displacement x engine speed)

[Alternative: calculate brake power from brake torque]

then

mass flow of fuel=bsfc x brake power

mass flow of exhaust= mass of fuel x (1+AFR)
