Description

Performs head losses calculations in curves with a known value of $\frac{R}{D}$, and in elbows ($\frac{R}{D}$ = 1). There are two options:

Given the flow

Given the flow, the pipe diameter and the relation $\frac{R}{D}$, calculates the corresponding head loss.

Coefficient

Given the pipe diameter and the relation $\frac{R}{D}$, calculates the head losses coefficients 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
