Q1: Steam Turbine - 2025 Real Question Problem : Calculate the work done by steam in a turbine if steam enters at 500°C, 10 MPa and exits at 50°C, 0.1 MPa. (Use steam tables for enthalpy values)
Solution :
Work done = h1 - h2 (where h1 = inlet enthalpy, h2 = outlet enthalpy)
h1 (at 500°C, 10 MPa) ≈ 3375 kJ/kg
h2 (at 50°C, 0.1 MPa) ≈ 209 kJ/kg
Work done = 3375 - 209 = 3166 kJ/kg
