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.
Where:
\Delta P | Pressure drop |
\rho | Fluid Density |
V | Fluid Velocity |
K values for different piping system equipment can be stored in the database for future application.
