Air is compressed from 140 kPa and 320 K to 1200 kPa in a two stage compressor with intercooling between stages. The intercooler pressure is 320 kPa. The air is cooled back to 320 K in the intercooler before entering the second compressor stage. Each compressor stage is isentropic. Use the PG model.

I am pretty sure this problem has two different pressure ratios for each compressor but I don't know how to find that pressure to find T3
Transcribed Image Text:**Compressor System with Intercooler**
Air is compressed from 140 kPa and 320 K to 1200 kPa in a two-stage compressor with intercooling between stages. The intercooler pressure is 320 kPa. The air is cooled back to 320 K in the intercooler before entering the second compressor stage. Each compressor stage is isentropic. Use the PG model.
**Diagram Explanation:**
- **Compressor Stage 1:** Air enters this stage at point 1 and is compressed to point 2.
- **Intercooler:** The air from point 2 is cooled back to a specified temperature before entering the second stage at point 3.
- **Compressor Stage 2:** Air enters this final stage at point 3 and is compressed further to point 4, the exit point.
**Part A:**
Determine the temperature (\(T\)) at the exit of the second compressor stage.
