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.
