###### Question: Problem Statement P, = 18 MPa Ti 1600K 2. (35 points) Heated and compressed air expands in an insulated turbine. The turbine produces 2800 kW of power during the process. The adiabatic turbine efficiency is given as 0.91. In solving the turbine performance, assume ideal gas behavior and that you can model the isentropic behavior using P constant. Finally, assume the constant pressure specific heat (Cp) is constant over the entire process at 1.005 kJ/kg-K and that the k for air is constant at 1.4. DO NOT USE TABLES. Find 2800 kW Gas Turbine (a) Outlet temperature of the air, Ta, in units of K (b) Mass flow rate of air through the turbine (kg/s) (c) Rate of change in entropy for the air (kW/K) P,-100kPa T-22
