Help me pls

Extracted text: Water vapor enters an adiabatic turbine with a pressure of 7 MPa and a flow rate of 2kg / sec at a temperature of 400 ° C, expanding up to 20 Kpa pressure. The adiabatic efficiency of the turbine is 0.8. Calculate the temperature of the steam at the turbine outlet and the power of the turbine, neglecting the kinetic and potential energy change of the steam.
