Determinação dos coeficientes de perda de carga aplicáveis a válvulas de gaveta completamente abertas

Default

Find the head loss coefficients for fully open gate valves.

Given the diameter and the passage area/pipe area of a gate valve, calculates de head loss coefficients applied to the formulae:

- For k applicable to:
$hf = \frac{k \cdot U^2}{2g}$
- For $k_Q$ applicable to:
$ℎf = k_Q\cdot Q^2$
