Process Description

The heat exchanger allows for heat to be transferred from a hot fluid to a cold fluid without mixing the two fluids. Figure 1 illustrates a counter-current heat exchanger process diagram.

Basis of Calculations

100 lb/hr of hot water

Solution Outline

1. Use HYSYS' shell and tube heat exchanger to model the process.
2. Define the inlet and outlet conditions for the streams as given in the problem statement.
3. Obtain the mass flow rate of the cold stream HYSYS.

Assumptions

1. The components behave according to the PRSV equation of state.
2. There is no heat loss to the environment.
3. The pressure drop across shell and tube is zero.
4. The  cold stream flow through the shell, while the hot stream flow through the tube.
