Coefficient

Performs head losses calculations in in 45° curves. There are two options:

Given the flow and the pipe diameter, calculates the corresponding head loss.

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

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