Question:
For the streams and flow configurations used in Example 20.1, what is the lowest temperature to which the gas stream can be cooled assuming the cooling water must leave the exchanger at 40°C?
Example 20.1
A gas is to be cooled from 100°C to 45°C using cooling water that enters the heat exchanger at 30°C and leaves at 40°C. What is the LMTD for the heat exchanger if the flow of the streams is 1. Countercurrent? 2. Cocurrent? 3. How much more heat-exchange area would be required for the cocurrent exchanger compared to the countercurrent exchanger?
