Design and Analysis of Heat Exchanger
Scenario:
You have been recently appointed as a junior engineer in reputed process engineering consultancy company, engaged to
provide detailed engineering for chemical manufacturing and related processes. As a part of technical team, your
supervisor asked you to complete several tasks related to thermal design and analysis of heat exchanger. Tasks mainly
includes analyze types of heat exchangers, thermal design of a) double pipe heat exchanger, b) single effect evaporator,
and c) condenser.

Page 3 of 9 Task 2 (Thermal Design of Double Pipe Heat Exchanger)
(45 Marks)
Perform thermal design and analysis of for given case of double pipe heat exchanger, and answer the following
Case:
A double pipe heat exchanger is used to cool A Sulfuric acid from B to C by D water with initial temperature E. The
internal diameter of inside and outside pipe are F and G respectively, while thickness of both pipes is 1.25 cm. Sulfuric
acid is flowing through the inside pipe.
