The Fluid Objects Palette contains objects for building dynamic models of hydraulic flow involving tanks, pipes, pumps, etc. The flow rate in the system is calculated by solving the unsteady Bernoulli equation.
The following objects are provided in the Fluid Objects palette.

Fluid Object Inputs
Keyword |
Description |
Previous |
The upstream component that feeds this component. |
Diameter |
The hydraulic diameter of the component. Equal to the inside diameter of a pipe with a circular cross-section. |
Fluid Object Outputs
Output Name |
Description |
FlowArea |
The cross-sectional area of the component. |
Velocity |
The velocity of the fluid within the component. |
ReynoldsNumber |
The Reynolds Number for the fluid within the component. Equal to (velocity)(diameter)/(kinematic viscosity). |
DynamicPressure |
The dynamic pressure of the fluid flow. Equal to (0.5)(density)(velocity^2). |
InletPressure |
