Hi!
I've been searching for a way to calulate flow through a heat exchanger (I have no measurement of the flow in question).
The problem is that I don't have the usual variables available. I have a pump that is frequency driven, and thus delivers an unknown flow.
What I do have:
- Pressure measured downstream the pump (upstream the HEX).
- Estimate on the pump head.
Is there a way to calculate either the head loss or the velocity directly from what I've listed above?
Best regards,
Andy
