King Fahd University of Petroleum & Minerals MECHANICAL ENGINEERING DEPARTMENT ME 458 DESIGN OF THERMO-FLUID SYSTEMS Spring Semester 2023-2024 (232) Assignment #2 1. Benzene is used for the manufacture of

detergent. A double pipe heat exchanger must be sized to exchange heat between benzene and water. The benzene flow rate is 1.26 kg/s, and it is to be heated from 23.9°C to 37.8°C. The water is available at 60°C. Select an appropriate heat exchanger and determine the required water flow rate. You must consider fouling affect such that the exchanger is to be cleaned on yearly basis. You need to provide a full report of your work including a Title page, Contents, list of figures and list of tables and References. All figures and references may be referred in the text, and the computer program should be included in the appendix at the end of the report. In addition, the report must include summary, an introduction, design methodology, presentation and discussion of results and findings and a conclusion.
