Pressure loss through heat exchanger
Pressure loss through heat exchanger
(OP)
Not sure if i have enough data to tackle this one. I have a 1" pipe with water at 60 psig going into a heat exchanger. The heat exchanger discharges water at a flow rate of 20 gpm. I am unable to access the heat exchanger, but i know its there. How do i determine the pressure at the discharege of this heat exchanger.
The goal is to discharge this into a pipe with about 5 psi but i need to determine if there is enough pressure to overcome a head difference and the 5 psi for the other pipe. will also need to check and see if the flow rate will be restriceted to a point that the heat exchanger will not be effective. any tips?
trying to get access to fathom but not sure i could properly set this up on there.
thanks

RE: Pressure loss through heat exchanger
You will need to know if the water you have is on the tube or shell side of the unit.
20 GPM through a 1" pipe has a velocity of about 7.4 ft/sec and 10.9 psi / 100 ft (per Crane 410)
For me this is on the high side.
You are missing some key information to proceed further.
What is the purpose of the exchanger?
Using water to heat or cool something?
Heating or cooling the 20 GPM of water you have?
Good luck.

guessing this thing needs to be cleaned out
