Superheated Steam at 150 PSIG Pressure & 450^{o}F Temperature is to be desuperheated to
15^{o}F above its saturation temperature using boiler feed water available at 150 psig & 250^{o}F.
Desuperheated steam to be produced at the rate of 5000 lb/hr.

- Visit Steam Tables IAPWS IF-97
- Select Properties at Pressure and calculate steam properties at 150 psig
- Saturation temperature of Steam at 150 psig is 365.872
^{o}F - Steam is to be desuperheated to 365.87 + 15 = 380.87
^{o}F - Change the Units in Desuperheating Calculation and input above values in yellow highlighted cells
