Valve

Lower the pressure isenthalpically (aka throttling).

Inputs

  • Outlet Pressure: Target downstream pressure (must be > 0).
  • Pressure Drop (deltaP): Pressure drop across the valve (must be > 0).
  • Specify exactly one of outlet pressure or pressure drop.

Outputs

  • Throttled outlet stream at the specified outlet pressure, or computed from inlet pressure and specified pressure drop (isenthalpic expansion, so no work output).

Warnings

  • Wrong sign: If the specified outlet pressure is higher than inlet pressure.
  • Invalid pressure drop: If the specified pressure drop (deltaP) is non-positive.
  • Specification conflict: If both outlet pressure and pressure drop are specified, or if neither is specified.
