Problem: Heat Exchanger Design for a Cooling System

Problem Description:

An industrial plant requires the installation of a heat exchanger to cool process water using atmospheric air. The heat exchanger must reduce the water temperature from

90 C

40 C .

The water flow rate is

10 k \frac{g}{s},

and the air used for cooling enters at

25 C

and exits at

60 C .

The available air flow rate is

30 k \frac{g}{s} .

Objectives:

Calculate the amount of heat that must be removed from the water.

Select a suitable heat exchanger and justify the choice.

Determine the heat transfer area and the overall heat transfer coefficient.

Propose a design that minimizes thermal losses and environmental contamination.
