CURVE:FUNCTIONAL:PRESSUREDROP

Sets up curve information for minor loss and/or friction calculations in plant pressure simulations Expression: DeltaP = {K + f*(L/D)} * (rho * V^2) / 2

Name

Type: alphanumeric

Diameter

Type: real number
"D" in above expression, used to also calculate local velocity
Unit: m

Minor Loss Coefficient

Type: real number
"K" in above expression
Unit: dimensionless

Length

Type: real number
"L" in above expression
Unit: m

Roughness

Type: real number
This will be used to calculate "f" from Moody-chart approximations
Unit: m

Fixed Friction Factor

Optional way to set a constant value for "f", instead of using internal Moody-chart approximations
