Description

This calculation determines the head loss in a strainer, a device used to retain solid particles in hydraulic systems.

Based on the strainer diameter and fluid flow rate, the calculation provides:

• The head loss coefficient $K_Q$, used in the equation $h_f = K_Q \cdot Q^2$.
• The velocity of the fluid exiting the strainer.
• The head loss caused by the fluid passing through the strainer.

These calculations help optimize strainer sizing and evaluate system efficiency.
