On the flow rate of water inside the cooling tubes of finned air coolers
Thread Content
Hello everyone. As the title suggests, regarding the flow rate of water inside the cooling tubes of finned air coolers, **is there any regulatory document or standard available? There is currently an air cooler, and the flow rate of the cooling water is 2.3 m/s; the customer requests evidence for the design rationale. It is a BFe10-1-1 tube
According to GB151-2014, the design flow rate should be determined through calculations based on the allowable pressure drop provided by the user.
The calculation is based on the pressure drop permitted by the customer, but the customer has asked us to provide a standard basis for using this flow rate
No, they are all selected after technical and economic comparisons; there are no fixed rules. There are only specified flow rate ranges for different water pipeline designs – 2–6 meters per second for high-pressure systems, while the upper and lower limits for low-pressure systems are lower.
Well, I’ve been looking for a long time as well, and I really can’t find any relevant **standards**. Thanks
People who design their own things don’t even know how they manage to do it – they’re also experts
It is on the high side; it is advisable to keep the flow velocity inside the pipe at around 1.5.
