Hi,

 

Im calculating  the pressure drop in a cooling tower, with the main branch of the pipeline passing through 4 shell-and-tube exchangers in parallel, of which 1 returns directly to the main return line and 3 exchangers combine into a single pipeline passing through 2 exchangers in series, returning the water to the cooling tower. My question is: should I segment the lines and calculate them separately? Should I use the Hazen-Williams method or the equivalent length method?

Thanks

Hi,

To support your query, consider these excel sheets. This could give you some ideas for your design.

Why don't you use Darcy Weisbach's equation instead of Hazen's equation or equivalent length?

Good luck,

Breizh
