A turbine operates under steady flow conditions, receiving steam at the following state: Pressure 1.2 MPa, temperature 188°C, enthalpy 2785 kJ/kg, velocity 33.3 m/s and elevation 3 m. The steam leaves the turbine at the following state: Pressure 20 kPa, enthalpy 2512 kJ/kg, velocity 100 m/s, and elevation 0 m. Heat is lost to the surroundings at the rate of 0.29 kJ/s. If the rate of steam flow through the turbine is 0.42 kg/s, the power output of the turbine in kW is 110.22 kW Other 102.81 kW -123.71 kW 112.51 kW O

Transcribed Image Text:A turbine operates under steady flow conditions, receiving steam at the
following state: Pressure 1.2 MPa, temperature 188°C, enthalpy 2785
kJ/kg, velocity 33.3 m/s and elevation 3 m. The steam leaves the turbine
at the following state: Pressure 20 kPa, enthalpy 2512 kJ/kg, velocity
100 m/s, and elevation 0 m. Heat is lost to the surroundings at the rate
of 0.29 kJ/s. If the rate of steam flow through the turbine is 0.42 kg/s, the
power output of the turbine in kW is
110.22 kW O
