Question

An adiabatic steam turbine in a small electric power plant is designed to accept 4500lg/hr of steam at 60 bar and 500°C and exhaust the steam at 10 bar.

In off peak hours the power output of the turbine is decreased by adjusting a throttling valve that reduces the turbine inlet stream pressure to 30 bar while keeping the flow rate constant (see Figure below) . What is the turbine inlet temperature, the steam temperature at the outlet of the turbine and the power output of the turbine?
