K Node

Node for representing pressure loss coefficient. It represents the directly proportional relationship of head loss (or pressure drop) to the square of velocity arriving to the expression:

\Delta P = K × (ρV²/2)

Pressure loss coefficients can be applied across different fluids. According to DS Miller, these coefficients are not unique to a specific fluid but instead function as universal relationships to Reynolds number for a given geometry.

K values for different piping system equipment can be stored in the database for future application.
