API RP 1102 Pipeline Local Pressure

Calculate API RP 1102 local pipeline stationary internal pressure from elevation.

Elevation is measured relative to any arbitrary datum (+ve above the datum -ve below the datum). The internal fluid density is assumed constant. Use the Result Plot option to plot pressure versus elevation.

CALCULATOR : API RP 1102 Local Pressure From Elevation [FREE]   ±

Calculate API RP 1102 pipeline local stationary pressure from elevation.

The local internal pressure is calculated from the reference pressure and relative elevation using Bernoulli's equation. The internal fluid density is assumed constant.

Tool Input

  • plitype : Internal Pressure Type
    • Priu : User Defined Reference Internal Pressure
    • Pliu : User Defined Local Internal Pressure
  • ρf : Internal Fluid Density
  • Zr : Reference Elevation Relative To Datum
  • Zl : Local Elevation Relative To Datum

Tool Output

  • Δz : Local Elevation Relative To Reference Elevation
  • Pli : Internal Pressure At Local Elevation
  • Pri : Internal Pressure At Reference Elevation
CALCULATOR : API RP 1102 Three Phase Fluid Density [FREE]   ±

Calculate API RP 1102 pipeline fluid density for three phase gas oil water (black oil).

Select either single phase oil, single phase water, two phase liquid (oil and water), single phase gas, or three phase gas, oil and water. Gas oil ratio (GOR) is measured relative to the oil volume at standard conditions (water volume is ignored). Water cut is the volume ratio of water in the liquid phase (water and oil - gas volume is ignored).
