Given the flow

Coefficient

Performs head losses calculations in gradual expansions. There are two options:

Given the flow and the inlet diameter of the gradual expansion, calculates the corresponding head loss.

Given the inflow pipe diameter, calculates the head losse coeficients corresponding to the expressions ℎf = k.U2/2g e e ℎf = kQ.Q2

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