Problem 55P

Steam enters a steady-flow turbine with a mass flow rate of 13 kg/s at 600°C, 8 MPa, and a negligible velocity. The steam expands in the turbine to a saturated vapor at 300 kPa where 10 percent of the steam is removed for some other use. The remainder of the steam continues to expand to the turbine exit where the pressure is 10 kPa and quality is 85 percent. If the turbine is adiabatic, determine the rate of work done by the steam during this process.

Step by step solution Step 1 of 3From the table of superheated water,write the initial enthalpy of steam when the initialpressure and initial temperature is respectively as,From the table of saturated water pressure table,write the final enthalpy of steam when thefinal pressure and quality at state 2 is respectively as,\nCalculate the enthalpy of steam at state as follows ............(1)Here enthalpy of saturated liquid is ,quality is , and enthalpy of vaporization is .From the table of superheated water,write enthalpy of vaporization and enthalpy of formation atthe pressure of and quality of 0.85as,respectively as,
