Gravity Pressure Change

fullflow.GravityPressureChange

Hydrostatic pressure change from elevation.

GravityPressureChange computes downstream pressure from upstream pressure, fluid density, gravitational acceleration, and elevation change. Positive elevation change is upward, so pressure decreases as elevation increases.

If mass flow is assigned, the component also computes an equivalent effective area for the resulting pressure drop.
