The inlet conditions of the gas are at the stagnation state (p0, T0) which are constants. The pressure at the exit plane of the nozzle is denoted by PE and the back pressure is PB which can be varied by the adjustment of the valve.

Back pressure is developed due to steam strike on blade. It's exit of pressure not back pressure.
