No of tubes in mutipass shell and tube heat exchangers
No of tubes in mutipass shell and tube heat exchangers

Hi,
Why the number of tubes in 2nd pass of the 2 pass shell and tube exchanger is higher than the no of tubes in the first pass.

RE: No of tubes in mutipass shell and tube heat exchangers
We have got a heat exchanger with more than 30 % variation in no of tubes in two passes. Inlet/ outlet sizes are different and there is one impingement plate installed for the shell inlet. 5-10% variation in tubes seems reasonable, but will 30% variation not be quite away from the best efficiency we could achieve with similar exchanger having equal number of tubes..
RE: No of tubes in mutipass shell and tube heat exchangers
A common requirement for shell and tube heat exchangers is that the number of tubes in any tube pass must be within +/- 10% of the average number of tubes per pass.

I'm pretty sure it's Ms. Christine.
I also think you'd get more help/replies if you changed your username.
Good Luck,
