Given the flow

Coefficient

Performs head losses calculations in sudden reduction. There are two options:

Given the flow and the inlet and outlet diameters of the sudden reduction, calculates the corresponding head loss.

$h_f = k. \frac{U^2}{2g}$

Given the inflow pipe diameter, calculates the head loss coeficients corresponding to the expressions:

- k applicable to the expression:
$h_f = k. \frac{U^2}{2g}$
- kQ applicable to the expression:
$h_f = k_Q. Q^2$
