Head loss

Description

Performs head losses calculations in sharp-edged inlet. There are two options:

Given the flow

Given the flow and the sharp-edged inlet diameter, calculates the corresponding head loss. $$ hf = k.U²/2g $$

Coefficient

Given the sharp-edged inlet diameter, calculates the head losses coefficients corresponding to the expressions:

  1. k applicable to the expression: $$ hf = k.U²/2g $$
  2. kQ applicable to the expression: $$ hf = kQ.Q² $$
