Compressor and Heat Exchanger Operations — Lesson - 5

This lesson covers the principles of compressor and heat exchanger operations, focusing on the properties of S gas, volumetric flow rate, and the calculation of compressor power and flow rate of cooling water. The lesson also delves into the concept of entropy change, using practical examples to illustrate how to calculate the total rate of entropy change. The lesson further explains the application of the first law of thermodynamics to individual components of a system, such as a compressor and a heat exchanger.
