constant-pressure heating device

1. A compressor in a refrigerator receives R-410a at 150 kPa, −40◦C and brings it up to 600 kPa, using an actual specific work of 58.65 kJ/kg in adiabatic compression. Find the specific reversible work.

2. Air flows through a constant-pressure heating device, shown in Fig. P8.27. It is heated up in a reversible process with a work input of 200 kJ/kg air flowing. The device exchanges heat with the ambient at 300 K. The air enters at 300 K, 400 kPa. Assuming constant specific heat, develop an expression for the exit temperature and solve for it by iterations.
