Air enters an adiabatic compressor at 100 kPa and 27 °C and leaves 550 kPa and 287 °C. Assuming constant specific heats, determine the isentropic efficiency of the compressor.

NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Air is compressed by an adiabatic compressor from 95 kPa and 27°C to 600 kPa and 277°C. Assume variable specific heats and neglect the changes in kinetic and potential energies. Determine the isentropic efficiency of the compressor. Use the table containing the ideal-gas properties of air. The isentropic efficiency of the compressor is 0 %.

Water steam flows steadily through an adiabatic turbine. The inlet conditions of steam are 1.0 x 106 Pa and 600°C, one of the exit conditions is 7.5 x 10³ Pa. Assuming the process is isentropic, determine (with the help of the steam table): (a) the temperature of the steam at the exit (K). (b) the quality of the steam at the exit (%). (c) the specific enthalpy of the steam at the exit (kJ/kg). (d) the work done per unit mass by the turbine (kJ/kg).

Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Steam flows steadily through an adiabatic turbine. The inlet conditions of the steam are 4 MPa, 500°C, and 80 m/s and the exit conditions are 30 kPa, 92 percent quality, and 50 m/s. The mass flow rate of the steam is 13 kg/s. The properties of the steam are = 0.086442 m³/kg, h=3446 kJ/kg, and 2 = 2437.7 kJ/kg. P₁-4 MPa T₁ - 500°'℃ V₁-80 m's P₂ - 30 kPa 32-0.92 Vyu 30 m/s Determine the change in kinetic energy. (You must provide an answer before moving on to the next part.) The change in kinetic energy is kJ/kg.
