HI SNORGY
0.21 ft/s is low because heat transfer resistance in Tube side, more than 75%. and also it is much lower than recommended tube velocity 2 ft/s. I can reduce number of tubes but with reducing NO. of TUBES, heat transfer area also will be reduced.
And 0.5" tube diameter and tube...
Dear all
I'm designing a shell & tube heat exchanger which it is supposed to be AES.
and it should only be 1 in parallel and series.
In periliminary design its sizes shell and Tube are 539-5500 mm respectively.
and its tube count is 367 with 0.75" Diameter. And my design spec do'nt let me to...
