Pressure drop and head loss calculation in an exchanger
- Calculating the pressure drop across a heat exchanger uses the equivalent diameter:
The pressure drop is the calculated pressure drop experienced by the fluid passing through the heat exchanger around the tubes..
- If you want to know the pressure drop of the fluid through the tubes, it suffices to calculate the pressure drop in one tube (onglet pertes de charge reguliere).
- If the tubes are in parallel load losses are balanced by distributing the flow rate, the pressure drop of all tubes is equal to the pressure drop of 1 tube.
- the head loss are added only if the tubes are in series (one after another)
