Description

Performs head losses calculations in contraction. There are two options:

Given the flow

Given the flow, the outlet diameter of the contraction and the reduction angle, calculates the corresponding head loss. $$ h_f = k. \frac{U^2}{2g} $$

Coefficient

Given the outflow pipe diameter and the reduction angle, calculates the head losses coeficients corresponding to the expressions:

1. k applicable to the expression: $$ h_f = k. \frac{U^2}{2g} $$

2. kQ applicable to the expression: $$ h_f = k_Q. Q^2

   $$
