Incorrect Units: Using the wrong units for flow rate or head can drastically change the calculation. Always use gallons per minute and feet, respectively. Overlooking Friction Losses: Failing to account for friction losses in total head can lead to underestimating WHP. Misinterpreting Total Head: ...
Best of all, if the answer is used as a variable in another equation, it will automatically be placed in any other such equation, allowing for rapid calculation of pump technical data. Pressure head Pressure (psi) Specific Gravity Head (ft) Total Dynamic Head Pumping Water Level from Datum...
