Description

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

Given the flow

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

Coefficient

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:
  $$ℎf = k_Q\cdot Q^2$$
