Refrigerant-22 absorbs heat from a cooled space at 50°F as it flows through an evaporator of a refrigeration system. R-22 enters the evaporator at 10°F at a rate of 0.08 lbm/s with a quality of 0.3 and leaves as a saturated vapor at the same pressure. Determine the second-law efficiency of the evaporator. Take T0 = 77°F. The properties of R-22 at the inlet and exit of the evaporator are: h1 = 107.5 Btu/lbm, s1 = 0.2851 Btu/lbm·R, h2 = 172.1 Btu/ lbm, s2 = 0.4225 Btu/lbm·R.

Air enters the compressor of a gas turbine plant at ambient conditions of 100 kPa and 25 ⁰C with a low velocity and exits at 1 MPa and 347 ⁰C with a velocity of 90 m/s. The compression process is adiabatic, and the power input is 271. Determine the mass flowrate of the air through the compressor.
Water at 20 psia and 500F enters a mixing chamber at a rate of 7 lbm/s where it is mixed steadily with steam entering at 20 psia and 2800F. The mixture leaves the chamber at a rate of 500 Ibm/min at 20 psia and 1600F, and heat is lost to the surrounding air at 700F at a rate of 200 Btu/min. Neglecting the changes in kinetic and potential energies, determine the rate of entropy generation during this process.
