Steam heat exchangers allow heat to transfer from primary heat source to a secondary fluid without direct contact. The two main exchange for this application are shell and tube and plate heat exchangers. You are required to design a shell-and-tube heat exchanger (using LMTD method) to heat water from 25°C to 89°C using steam at 335°C. The steam enters at the shell side at a velocity of 5 m/s. The design should adhere to the design constraints stated below: Design constraints: Due to space limitation, the tube length must not longer than 1 m. Due to pump capacity, the maximum amount of steam will not exceed 1.5 kg/s. There is no phase change in the fluids. You are required to provide a report containing: (1) Introduction of heat exchanger and its design, (2) Design calculations, and (3) Discussion on the heat exchanger design. List of Appendices should also be included in the report for all the reference data used, e.g. thermal conductivity of the solid material, thermophysical properties of the fluid, and etc. All references should be cited according to the APA format. Assumptions made in the calculations should be justified. The design calculations should contain the followings, but not limited to: Amount of water can be heated up to desired temperature Heat transfer area Number of tubes and its dimension Number of passes Based on your design, 1. Investigate the relationship between: (i) (ii) Mass flow rate of water with heat transfer rate Mass flow rate of water with heat transfer area 2. Determine the convection heat transfer coefficient inside the tube.
