Hi there!
Is there anyone who can tell me how you can calculate the pressure drop in a 5-sections bending of 180 degrees, where the inner radius is nearly zero?
I´m talking about a square duct with the following measurements:
section 1: 0.496 mtr
section 2: 0.354 mtr
section 3: 0.251 mtr...
By not precise enough charts I mean that the charts I have are not for use with the exchanger I have. I am calculating a 4-pass crossflow heat exchanger and all charts I have found are for "more simple" exchangers or just 1-pass cross flow.
Tnx for your post siretb!
Hi there,
@ tickle: Thanks for your answer, I only need the correction factor for the LMTD, not the calculation for a MTD itself.
@ 25362: I need this formulas because I am working on a effectivity calculation for a specific crossflow heat exchanger and I would like to calculate the EMTD...
Is there anyone who can tell me what the equation for the correction factor of a LMTD in a crossflow heat exchanger is? I only can find charts of this correction factor, but no equation...
