Turbine are useful devices. For example, steam flows at steady state into a poorly insulated turbine at a rate of 2.94 kg/s. The heat transfer from the turbine is 9.83 kW. At the inlet, the conditions are: 2.0 MPa, 350 C, 48.6 m/s, and 7.64 m above the datum. At the exit, the conditions are: 0.1 MPa, 100% quality, 97.3 m/s, and 2.56 m above the datum. Note: The IUPAC sign conversion for work is used. Work into the system has a positive value. Determine the power output of the turbine. power output: kW Solve for the power output of the turbine again, but assume that changes in the kinetic and potential energy are negligible. What is the percent difference in the power output by making this assumption? percent difference in power output: % Turbines are useful devices. Argon gas enters an adiabatic turbine at 786.0 kPa and 372.0 C with a velocity of 87.4 m/s and leaves at 153 kPa with a velocity of 199.0 m/s. The inlet area of the turbine is 79.9 cm. The power output of this turbine is 258 kW. Argon can be assumed to be an ideal gas with MW = 40.0 g/mol and Cp = 0.5203 kJ/kg C. = Note: The IUPAC sign convention for work is used. Work into the system has a positive value. What is the exit temperature? exit temperature: K
