For shell-and-tube coolers or internal coil heat exchangers, what pressure difference is required at the inlet and outlet of the fluid to meet the requirements? Or what is the magnitude of the pressure drop?
It seems that it depends on the properties of the material, and the relationship with pressure difference isn’t that significant; what’s important is the flow rate
What was said on the second floor makes sense; thanks for sharing it!
Final answer: The pressure difference ΔP must satisfy: ensuring the required flow velocity u at the tube length L of the heat exchange tube.
Ensuring an appropriate flow rate is necessary to prevent deposition and corrosion. When establishing specifications, the pressure difference is specified; the main calculation tools (including software) help determine whether the values are reasonable and what the outcomes will be. In practical terms, it’s best to have as low a pressure difference as possible, in order to avoid losses during fluid flow
This is related to both the designed structure and the medium; different viscosities of the medium, along with the structure itself, determine the flow rate. The ones I have designed range from over ten thousand pascals to over a hundred thousand pascals
