Description

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

Given the flow

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

Coefficient

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:
  $$h_f = k_Q. Q^2$$
