Steam enters a turbine operating at steady state with a mass flow 10 kg/min, a specific enthalpy 3100 kJ/kg, and a velocity of 30 m/s. At the exit, the enthalpy is 2300 kJ/kg, velocity 45 m/s. The elevation of the inlet is 3m higher than the exit. Heat transferred away from the turbine is 1.1 kJ/kg of stream flow. Let g = 9.81 m/s2. Find the velocity and elevation heads (in kJ/kg) V12/2 , V22/2 , and g(z1-z2); and work output Ws from turbine in kW.
