Problem 116HP
A two-stage compressor takes nitrogen in at 20°C, 150 kPa and compresses it to 600 kPa, 450 K. Then it flows through an intercooler,where it cools to 320 K, and the second stage compresses it to 3000 kPa, 530 K. Find the specific work in each of the two compressor stages and the specific heat transfer in the intercooler.

Problem 116HP
A two-stage compressor takes nitrogen in at 20°C, 150 kPa and compresses it to 600 kPa, 450 K. Then it flows through an intercooler,where it cools to 320 K, and the second stage compresses it to 3000 kPa, 530 K. Find the specific work in each of the two compressor stages and the specific heat transfer in the intercooler.
ANSWER:
Solution 116HP
Step 1 of 5
Here we have to calculate the specific work for each compressor and the specific heat transfer in the intercooler, for the given two stage compressor with nitrogen.
The given process can be pictorially represented as shown below,
