King Fahd University of Petroleum and Minerals Mechanical Engineering Department ME 315: HEAT TRANSFER (122), Course Project (10 %) Due date: Saturday, May 11, 2013, each day delay, -1% point Type of heat exchanger: Shell and tube with two tube passes and one shell pass. You are given the assignment to design a heat exchanger whose length should not exceed 5 m (length of the heat exchanger not the tube). The aim of this project is to increase your ability to solve real world problems which are characterized to be ill-posed. That is, the given data is not enough to solve the problem and thus you have to make some decisions and careful assumptions such that you can solve the problem. The objective of the heat exchanger is to heat water at 9 kg/s from 20 to 60oC, which is inside the tubes. The heating medium, in the shell side, is saturated steam at 150 kPa and it is condensing on the outer side of the tubes and has a condensing heat coefficient of 8000 W/m2-K. The outer diameter of the tube is 2 cm and the wall thickness is 0.3 cm. It is expecting that the inside tube to have a fouling coefficient of 5000 W/m2-K. The water pressure inside the tube is 101 kPa. Requirements: 1-Find the total length of the tube per pass. You need to assume several values of the total number of tubes until your reach to a value of L just smaller than 5 meter. You need to use three different materials of the tubes (different thermal conductivities: k= 50, 100, and 200 (W/m-K.) Plot the length vs. total number of tubes for the three cases. 2-For the case in part 1 re-solve the same problem and neglect the fouling resistance. 3-Discuss in details your observations in each part, and then compare part 1 and 2. Note: you need two figures (one for part 1 and one for part 2) You need to organize your report as follow (write the section headlines): a) Cover page. b) Problem statement. c) Given data in the proper units. d) What are required to find. e) Assumptions. f) Sketch (Draw simply shell and…
