Calculation Notes

The basic horsepower formula, PHP=q⋅p1714PHP = \frac{q \cdot p}{1714}, assumes a pump operating at 100% efficiency. In real-world applications, this is never the case. It's crucial to account for the pump's overall efficiency (μ\mu) to determine the actual required input power.

The modified formula, PHP=q⋅p(μ100)⋅1714PHP = \frac{q \cdot p}{\left(\frac{\mu}{100}\right) \cdot 1714}, incorporates this efficiency factor, where μ\mu is the overall efficiency expressed as a percentage. Typical hydraulic pumps have an overall efficiency range of 80% to 95%.
