Important Notes:

This is a group project. Each project will consist of five members. You should submit a professional report substantiating your findings. The report should contain an introduction (max 3 pages), methodology, assumptions, equations, results & discussion, conclusion and a one-page individual section reflecting on your learning.

Show your calculations in the Appendix. If your calculations include an iterative process; a minimum of one complete iteration should be shown in detail.

Your solution for the problems described below must follow a logical solution method, be complete, with all work shown

Incomplete or partial solutions will receive little partial credit.

Sign Pledge:

I have neither given nor received unauthorized aid on this project nor have I discussed the contents of this test with anyone before taking it.

Objectives

To check whether an existing heat exchanger would be suitable to perform a specific duty. Also estimate the tube and shell side pressure drop.

Project Description:

In a food processing industry there is a requirement to heat 40000 kg/h of town water from 20 to 80 °C. Steam at 3 bar pressure is available for heating the water. An existing heat exchanger is available with following configurations:

Shell inside diameter 337 mm, E type

Baffles 25% cut, set at a spacing of 106 mm

Tubes 15 mm inside diameter, 19 mm outside diameter, 4049 mm long

Tube pitch 23 mm, triangular

Number of tubes 124, arranged in single pass

Notes:

List all your assumptions.

Keep in mind the temperatures of the two streams when determining the properties of the two fluids. List all the fluid properties used in a table.
