In a steam power plant, superheated steam at 10 MPa and 500°C, is expanded isentropically in a turbine until it becomes a saturated vapour. It is then reheated at constant pressure to 500°C. The steam is next expanded isentropically in another turbine until it reaches the condenser pressure of 20 kPa. Relevant properties of steam are given in the following two tables. The work done by both the turbines together is ______ kJ/kg (roundoff to the nearest integer).

    Correct answer is '1513'. Can you explain this answer?

    In a steam power plant, superheated steam at 10 MPa and 500°C, is ...
    Given data: h1 = 3373.6 kJ/kg, h3 = 3478.4 kJ/kg, h2 = 2778.1 kJ/kg, s1 = s2 (as from table)

    s3 = s4
    s3 = 7.7621 = 0.8319 + x + (7.9085 – 0.8319)
    x4 = 0.9793
     h4 = hf + x4 × (hg – hf) = 2560.91 kJ/kg
    WT =(h1 – h2) + (h3 – h4) = 1512.95 kJ/kg
