Question A3 a. A closed system containing 2 kg of air undergoes an isothermal process from 600 kPa and 200 °C to 80 kPa. Determine: i) The initial volume of this system [20%) Answer: 0.4525 m ii) The energy transfer of this process [20%) Answer: 0.547.1 m b. Steam flows steadily through an adiabatic turbine. The inlet conditions of the steam are 6 MPa, 400 °C and 80 m/s, and the exit conditions are 40 kPa, 92% quality and 50 m/s. The mass flow rate of the steam is 20 kg/s. Determine: i) The change in kinetic energy (per kg) [20%) Answer: 1.95 kl/kg ii) The power output [20%] Answer: 14.6 MW iii) The turbine inlet area [20%] Answer: 0.0119 m
