Description

Performs head losses calculations in in 45° elbows. There are two options:

Given the flow

Given the flow and the pipe diameter, calculates the corresponding head loss.

Coefficient

Given the pipe diameter, calculates the head losses coeficients corresponding to the expressions:

• k applicable to the expression:
  $$h_f = k. \frac{U^2}{2g}$$
• kQ applicable to the expression:
  $$h_f = k_Q. Q^2$$
