Head loss coefficient applicable to partially open y valve

Input data

DIameter

Opening section

Output data

k applicable to h = k.U²/2g

kQ applicable to h = kQ.Q²

Description

Find the head loss coefficients for partially y valves.

Given the diameter and the opening relation of an y valve, calculates the head loss coefficients , for the expressions:

  1. For k applicable to:
    hf=k⋅U22⋅g hf = \frac{k \cdot U^2}{2\cdot g}
  2. For kQk_Q applicable to:
    hf=kQ⋅Q2 ℎf = k_Q\cdot Q^2
