MASS FLOW RATE CALCULATIONS. FOR STEAM INTO TURBINE

Mass Flow Rate through Steam Turbine Nozzle

Area of the Steam Turbine Nozzle

Pt := 0.480537MPa

From the Steam Tables for the given pressure and temperature

Since the inlet temperature is higher than the saturation temperature, the steam is superheated.
