Heat exchanger resistance
Thread Content
Hello everyone. I currently have a series of tubular heat exchangers, and I have two options: 1. Two flow paths with a flow rate of 230 cubic meters per hour; 2. Four flow paths with a flow rate of around 400 cubic meters per hour. I would appreciate it if experienced experts could help me determine what the pressure losses would be in each of these cases Which one is more reasonable to choose? Thank you!
Based on the information you provided, I am unable to estimate the pressure loss due to my lack of experience. However, the pressure drop of the pipe train is related to the number of pipe trains you choose, and it is proportional to the cube of that number; the more pipe trains there are, the greater the resistance. The shell-side pressure drop is related to the baffle spacing you choose, and is essentially proportional to the cube of (1/B). B is the baffle spacing; the smaller the spacing, the greater the resistance. I hope this helps you.
Calculating the pressure drop requires taking into account many factors such as the flow velocity of the fluid, the properties of the fluid, and the length of the pipe. The conditions you provided are not complete!
2# Pengge, thank you for your answer; it’s been very enlightening for me!
The conditions are incomplete, so it is not possible to calculate the resistance.
