Hydraulic Efficiency (\( \xi_h \)):

\[ \xi_h = \frac{H \times Q}{P \times 33000} \times 100 \]

Where:

• \( \xi_h \) is the hydraulic efficiency, in percentage (%).
• \( H \) is the head, in feet (ft).
• \( Q \) is the mass flow rate, in pounds per minute (lb/min).
• \( P \) is the power input, in horsepower (hp).
