Let ma be the mass of air into turbojet, mf be the mass of fuel supplied in one second
By mass conservation during combustion reaction, the exhaust gases will have mass ma + mf
Here,
Mass flow rate of air to the turbojet = 1 kg/sec
Mass flow rate of fuel supplied = mf kg/sec
Mass of gases leaving will be 1 + mf kg/sec
