The mass flow rate into a steam turbine is 1.5 kg/s and heat transfer from the turbine is estimated at 8.5 kW. The properties of the steam at inlet and outlet of the turbine are as follows: Inlet outlet Enthalpy (kJ/kg) 3137 2675.5 Velocity (m/s) 80 200 Elevation (m) 3 1. Calculate the change of enthalpy across the turbine kJ/kg and kW Calculate the change in kinetic energy across the tubine kJ/kg and kW 2. 3. Calculate the change of potential energy across the turbine kJ/kg and kw 4. What is the power output of the turbine? 37 The mass flow rate into a steam turbine is 1.5 kg/s and heat transfer from the turbine is estimated at 8.5 kW.
