Discussion Overview

The discussion revolves around the relationship between flow rate and pressure in the context of pump operation. Participants explore whether knowing the flow rate of a pump allows for the determination of its pressure, particularly in the absence of a pump curve.

Discussion Character

  • Technical explanation, Debate/contested

Main Points Raised

  • Some participants suggest that knowing the flow rate can determine the pressure if a pump curve is available.
  • Others argue that without a pump curve, it is not possible to ascertain the pressure solely from the flow rate.
  • A participant mentions contacting the manufacturer for a pump curve as a potential solution.

Areas of Agreement / Disagreement

Participants express disagreement regarding the ability to determine pressure from flow rate without a pump curve, indicating that the discussion remains unresolved.

Contextual Notes

The discussion highlights the dependence on having a pump curve and the limitations of determining pressure based solely on flow rate.

If we know the flowrate of a pump, is it possible to find out the pressure of the pump?

Yes...if you have a pump curve.

The problem is I don't have one

In that case you cannot find the pressure knowing only the flow rate of the pump.

Contact the manufacturer of the pump, they will give you one.
