Pump Head Calculation Formula
The Pump Head Calculation Formula is quite simple, yet it can be daunting to calculate by hand. It is calculated using the following formula:
Pump Head = (Pressure Head + Elevational Head + Friction Head) / Specific Gravity
However, we understand that you are mainly interested in the breakdown of the table, so let’s dive right into that.
Categories/Types/Range/Levels of Pump Head Calculations and Results Interpretation (Imperial System)
The table below provides an overview of the different categories, types, range, and levels of Pump Head calculations and their corresponding interpretation in the Imperial System.
| Category | Range | Interpretation |
|---|---|---|
| Low Pump Head | 0 – 50 ft | Poor flow |
| Medium Pump Head | 50 – 100 ft | Moderate flow |
| High Pump Head | 100 – 150 ft | Good flow |
| Very High Pump Head | 150+ ft | Exceptional flow |
Examples of Pump Head Calculations (Imperial System)
Let’s face it; most of us are not keen on numbers, but we’ll try to make this as painless as possible. Below are some examples of Pump Head Calculation in the Imperial System. We have included the data for each individual in one row for easy comparison.
| Name | Pressure Head (ft) | Elevational Head (ft) | Friction Head (ft) | Specific Gravity | Pump Head Calculation |
|---|---|---|---|---|---|
| John | 20 | 50 | 30 | 0.9 | (20+50+30)/0.9 = 100.00 ft |
| Jane | 10 | 40 | 20 | 1.1 | (10+40+20)/1.1 = 59.09 ft |
| Bob | 25 | 60 | 50 | 0.95 | (25+60+50)/0.95 = 146.32 ft |
We hope that these examples have made the concept of Pump Head Calculation more digestible.
