A 1.0 m3 tank, initially filled with 103. kPa, 300. K air, is connected to a source of air at 1,500. kPa, 300. K. The tank slowly fills until it is at the same pressure. If the temperature is maintained at 300. K throughout this transient process, what is the total heat transfer required? (You can assume air is an ideal gas.)

Air enters the compressor at 100 kPa, 300 K and is compressed to 1000 kPa. The temperature at the inlet to the first turbine stage is 1400 K. The expansion takes place isentropically in two stages, with reheat to 1400 K between the stages at a constant pressure of 300 kPa. A regenerator having an effectiveness of 100% is also incorporated into the cycle. The turbine and the compressor each have am isentropic efficiency of 80%. Determine the following: (a.)...
