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 hf = k.U²/2g

Coefficient

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

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