A customer requested the design of a Heat Exchanger and provided the following information to the Engineering Department. In his factory, as part of the process upgrade, there is a need to heat 97.2 m³/hr of cold water from 32^oC to 60^oC. The heat is available from 100.8 m³/hr of hot water at 90^oC. The customer does not know of any other information that could lead to a final configuration of heat exchanger type. In this initial stage, he requires a preliminary design that can be evaluated to determine what additional requirements should be considered.

In a meeting conducted at the Engineering Department, it was decided to:

a) Design the Heat Exchanger with the information provided. In this stage, all assumptions must be listed and explained for customer evaluation and review.

b) Prepare Heat Exchanger drawings of the proposed solution/s.

c)  At the same time, the design must be evaluated to identify features and configurations that could be discussed with the customer with the aim of developing more complete specifications.

d) Cost analysis in not required.
