AS 2885.1 Pipeline Fluid Velocity And Flow Rate

Calculate AS 2885.1 pipeline fluid velocity and flow rate for two phase gas liquid piping, and three phase black oil piping (gas water and oil).

The two phase fluid calculator can be used for single phase gas, single phase liquid, or two phase gas and liquid. The three phase black oil calculator can be used for single phase oil, single phase water, two phase oil and water, and three phase oil, water and gas. Water cut is the volume fraction of water in the liquid phase (ignoring the gas phase). Gas oil ratio (GOR) is the ratio of gas moles to liquid volume (ignoring the water phase). Gas moles are commonly measured as gas volume at standard conditions, eg SCM (Standard Conditions Meter) or SCF (Standard Conditions Feet).

CALCULATOR : AS 2885.1 Two Phase Gas Liquid Velocity And Flowrate [FREE]   ±

Calculate AS 2885.1 pipeline fluid velocity and flowrate for two phase gas liquid.

Fluid velocity and flowrate can be calculated for single phase fluid, single phase gas, and two phase gas liquid. Gas oil ratio (GOR) is the ratio of gas moles over oil volume. Gas moles are commonly measured as gas volume at standard conditions (eg SCF or SCM).

CALCULATOR : AS 2885.1 Three Phase Black Oil Velocity And Flowrate [PLUS]   ±

Calculate AS 2885.1 pipeline fluid velocity and flowrate for three phase gas, oil and water (black oil).

Black oil is a three phase mixture of oil, water and gas. Fluid velocity and flowrate can be calculated for single phase oil, single phase water, single phase gas, two phase oil and water, or three phase gas, oil and water. Water cut is measured relative to the total liquid volume (gas volume is ignored). Gas oil ratio (GOR) is measured relative to the oil volume at standard conditions (water volume is ignored).

CALCULATOR : AS 2885.1 Single Phase Gas Velocity And Flowrate [FREE]   ±

Calculate AS 2885.1 pipeline fluid velocity and flowrate for single phase gas.

Gas molar mass is approximately equal to the molar mass of dry air times the gas specific gravity at standard conditions (for most gases the compressibility factor Z is approximately equal to 1 at standard conditions). The molar mass of dry air is taken as 28.964 kg/kg-mole. For gas mixtures, gas specific gravity is easier to measure than the molar mass.
