A turbine receives 0.4433 kg/s of R-134a steadily at 800 kPa and 40C . The refrigerant leaves the turbine at 120 kPa and a quality of 0.86. The turbine inlet and outlet velocities are 99 m/s and 11 m/s respectively. This turbine loses energy by heat transfer at a rate of 1.235 kW. Determine the power (kW) produced by this turbine. Determine the flow work per unit mass (kJ/kg) at the turbine inlet. All work must be shown. Draw a sketch identifying your system(s). Use appropriate schematics. Include energy arrows! Start your solution with a symbolic equation from a formula sheet. Simplify and briefly explain. Identify the source of your property information. Assume all given values are known to 4 significant digits or match the resolution from property tables. If you need values from a property table please specify and i will provide those for you. We use Cengel Boles 7e Appendices for our property values
