CALCULATOR MODULE : API RP 14E Maximum Erosional Velocity ±
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).

CALCULATOR MODULE : API RP 14E Fluid Velocity ±
Calculate API RP 14E fluid velocity and flowrate for single phase gas, single phase liquid, two phase gas liquid, and three phase gas, oil and water (black oil). Flow rate can be calculated for mass flow rate, volume flow rate, mole flow rate and velocity. Gas density is calculated from temperature and pressure, and either specific gravity or molar mass. Liquid density can be calculated from specific gravity, degrees Baume, degrees Twaddell, or degrees API. Black oil is a three phase mixture of oil, water and gas. 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 MODULE : API RP 14E Piping Wall Thickness ±

CALCULATOR MODULE : API RP 14E General Gas Piping Pressure Loss Equation ±
Calculate API RP 14E gas piping pressure loss from the general equation. The pressure loss is calculated using the Darcy-Weisbach form of the Moody diagram. For low Reynolds numbers Re < 2000, the fluid flow is laminar and the Hagen-Poiseuille laminar flow option should be used. In the transition region 2000 < Re < 4000, the flow is unstable and cannot be reliably calculated. For turbulent flow (Re > 4000), either the original Colebrook White equation or the modified Colebrook White equation can be used. Minor losses are used to account for pipeline fittings such as bends, tees, valves etc. Reference : API 14E Recommended Practice For Design and Installation of Offshore Production Platform Piping Systems Change Module : Related Modules : |

Calculate API RP 14E gas piping pressure loss from the Weymouth equation. The Weymouth equation was developed for fully developed turbulent flow in long pipelines. It is not suitable for low Reynolds number, or short piping sections. Minor losses are used to account for pipeline fittings such as bends, tees, valves etc. Compare the results for the Weymouth equation, the general equation (Moody diagram), and the Panhandle A and B equations.

CALCULATOR MODULE : API RP 14E Piping Mass And Weight ±
Calculate API RP 14E platform piping unit mass (mass per length), unit weight (weight per length), and total mass from length. The mass per joint can be calculated from the joint length. Construction quantities can be calculated from the total pipe length. Pipe mass and pipe unit weight (weight per length) can be calculated for multi layer pipelines (dry empty, dry full, wet empty and wet full pipelines). For multi layer pipelines, the first internal layer is the line pipe. Change the number of layers on the setup page. The line pipe layer diameter and thickness are calculated from the pipe schedule. Use the Result Table option to display a table of pipe mass and weight versus wall thickness for the selected diameter.
