Question:

A two-stage air compressor has an intercooler between the two stages, as shown in Fig. P10.35.

The inlet state is 100 kPa, 290 K, and the final exit pressure is 1.6 MPa. Assume that the constant pressure intercooler cools the air to the inlet temperature, T3 = T1. It can be shown that the optimal pressure is P2 = (P1P4)1/2 for minimum total compressor work. Find the specific compressor works and the intercooler heat transfer for the optimal P2.
