    1. The problem statement, all variables and given/known data
    air at a pressure of 30 bar and a temperature of 400 degrees expands through a turbine to a pressure of 0.2 bar. if the isentropic efficency is 80% determine the power developed for a mass flow rate of 300 KG/s

    2. Relevant equations

    Cv=0.715 KJ/Kg. K, Cp= 1.004 KJ/Kg.K

    3. The attempt at a solution
