Head loss coefficient in pipe stretches

Description

The head loss coefficient in pipe stretches is a key parameter in the design of hydraulic systems, determining the pressure loss due to internal friction in pipes. This coefficient can be calculated using different approaches, depending on the available information:

1. Velocity unknown: Determines the coefficient without prior knowledge of the fluid velocity.
2. Velocity known: Calculates the coefficient considering a predefined flow velocity.
3. Friction factor known: Evaluates head loss when the friction factor is already known.

The calculated value for the head loss coefficient $k_Q$ is such that $h_f=k_Q \cdot Q^2$.
