A steady mass flow rate (m1) of superheated steam flows through a turbine used in a power plant to drive an electric generator. The superheated steam enters the adiabatic turbine at a pressure of P1 and a temperature of T1. The steam expands in the turbine until it exits at a pressure of P2. The turbine has an isentropic efficiency of N . Determine the following given the properties listed below. m1(kg/s) = 45
P1(MPa) = 10
T1(C) = 525
P2(bar) = 0.4
N(%) = 80
1. Determine the specific enthalpy (kJ/kg) at the turbine inlet.
2. Determine the specific entropy (kJ/kg) at the turbine inlet.
3. Determine the specific enthalpy (kJ/kg) at the turbine exit if the turbine was isentropic.
4. Determine the actual specific enthalpy (kJ/kg) at the turbine exit.
5. Determine the power output (MW) of the turbine.
