public class DuctPressureDropData : IDisposable

The DuctPressureDropData type exposes the following members.

Properties
 NameDescription
Public propertyCategoryId The category id of duct curves. It will be OST_DuctCurves, OST_FlexDuctCurves, or OST_PlaceHolderDucts.
Public propertyCoefficient The coefficient of the duct.
Public propertyDensity The density of the duct. Units: (kg/ft³).
Public propertyDynamicViscosity The dynamic viscosity of the air in the duct. Units: (kg/(ft*s)).
Public propertyFlow The flow of the duct. Units: (ft³/s).
Public propertyFriction The friction of the duct. Units: (kg/(ft²·s²)).
Public propertyHeight The height of the duct. If the duct is round, it will be equal to the diameter of the duct. Units: (ft).
Public propertyHydraulicDiameter The hydraulic diameter of the duct. Units: (ft).
Public propertyIsValidObject Specifies whether the .NET object represents a valid Revit entity.
Public propertyLength The length of the duct. Units: (ft).
Public propertyLevel The calculation level of the system.
Public propertyPressureDrop The pressure drop of the duct. Units: (kg/(ft·s²)).
Public propertyReynoldsNumber The reynolds number of the duct.
Public propertyRoughness The roughness of the duct. Units: (ft).
Public propertyShape The profile type of the duct.
Public propertyVelocity The velocity of the duct. Units: (ft/s).
Public propertyVelocityPressure The velocity pressure of the duct. Units: (kg/(ft·s²)).
Public propertyViscosityObsolete.
The kinematic viscosity of the air in the duct. Units: (ft^2/s).
Public propertyWidthOrDiameter The diameter of the duct with round profile, or the width of the duct with other profiles. Units: (ft).
