Two Phase Fluid Flow Modules

Calculate API RP 14E maximum allowable erosional velocity for platform piping systems.

The fluid density can be calculated for single phase gas, single phase liquid, two phase gas liquid, or three phase black oil (gas oil and water). The erosional velocity is calculated from the fluid density and the C Factor. Equation 2.14 in API RP 14E uses FPS units. The API RP 14E calculators have been factored to use SI units.

For fluids with no entrained solids a maximum C value of 100 for continuous service, or 125 for intermittent service can be used. For fluids treated with corrosion inhibitor, or for corrosion resistant materials a maximum C value of 150 to 200 may be used for continuous service, and upto 250 for intermittent service. For fluids with solids, the C value should be significantly reduced.

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). Water cut is the volume ratio of water in liquid (oil and water).

Calculate dynamic and kinematic viscosity for two phase gas liquids (gas and oil or gas and liquid).

Kinematic viscosity is equal to the dynamic viscosity divided by the density of the fluid. The viscosity of two phase fluids and mixtures can be calculated from the dynamic viscosity and the volume fraction. The gas oil ratio is the ratio of gas moles to oil volume. It is often measured as gas standard volume (scf or scm) per oil volume (barrels, gallons, cubic feet or cubic meters).

Calculate two phase gas liquid heat capacity.

Fluid heat capacity can be calculated for single phase phase liqui. single phase gas, or combined liquid and gas. Gas oil ratio (GOR) is the ratio of gas moles over liquid volume. Gas moles are commonly measured by standard cubic feet (scf), and stand cubic meters (scm). Gas oil ratio is often measured as gas standard volume (scf or scm) per oil volume (barrels, gallons, cubic feet or cubic meters).
