# 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
