CALCULATOR Convert Darcy Friction Factor Fanning Friction Factor Darcy Transmission Factor And Fanning Transmission Factor
Convert DarcyWeisbach friction factor, Fanning friction factor, DarcyWeisbach transmission factor and Fanning transmission factor.
The Darcy friction factor and Fanning friction factor are often converted to transmission factors for gas flow equations. The Fanning friction factor is equal to the DarcyWeisbach friction factor divided by 4. The transmission factor is equal to the inverse of the square root of the friction factor.

CALCULATOR Gas Liquid And Two Phase Fluid Density
Fluid density for single phase fluid, single phase gas, and two phase gas liquid.
For two phase fluids the fluid density and composition may be calculated from either the average fluid density, the gas oil ratio GOR, the gas mass fraction, the gas volume fraction, or may be user defined.

CALCULATOR Gas Liquid And Two Phase Rectangular Duct Mass Volume And Line Pack
Calculate rectangular duct line pack volume.
Generally gas ducts are of limited use for storage because of their limited internal pressure.

CALCULATOR Gas Pipeline Average Flowing Temperature And Pressure
Gas pipeline average temperature and pressure.
In general, pipeline temperature decays exponentially along the length of the pipeline, and the pressure drops in proportion to the distance squared. The average temperature and pressure are approximate only.
For average temperature, the ambient temperature and the pipeline insulation is assumed to be constant along the length of the pipeline. The inlet and outlet temperature must be either both above the ambient temperature, or both below the ambient temperature, and may not be equal to the ambient temperature.
For average pressure, the pipe slope is assumed to be constant along its length.

CALCULATOR Liquid Pipeline Average Flowing Temperature And Pressure
Liquid pipeline average temperature and pressure.
In general, pipeline temperature decays exponentially along the length of the pipeline, and the pressure drops linearly. The average temperature and pressure are approximate only.
For average temperature, the ambient temperature and the pipeline insulation is assumed to be constant along the length of the pipeline. The inlet and outlet temperature must be either both above the ambient temperature, or both below the ambient temperature, and may not be equal to the ambient temperature.
For average pressure, the pipe slope is assumed to be constant along its length.

CALCULATOR MODULE Gas Pipeline Pressure Loss
Moody Diagram Friction Loss Calculators : Friction losses are calculated using the DarcyWeisbach equation and the Moody Diagram. For low Reynolds numbers Re < 2000, the fluid flow is laminar and the Darcy friction factor should be calculated using the HagenPoiseuille laminar flow equation. For high Reynolds numbers Re > 4000, the fluid flow is turbulent and the Darcy friction factor should be calculated using either the ColebrookWhite or Modified ColebrookWhite turbulent flow equation. In the transition region 2000 < Re < 4000, the flow is unstable and the friction loss cannot be reliably calculated.
Minor losses can be entered as either a K friction factor, a length, or a length over diameter ratio. The minor losses are used to account for pipeline fittings such as bends, tees, valves etc.. The pipeline efficiency factor can be used to account for pipe condition, and other flow restrictions such as debris, and rust etc...
Use the goal seek page to calculate the flow rate, or diameter. Liquid flow rate can be defined by either volume flow rate, mass flow rate, or velocity. The calculated pressure change due to change in elevation is approximate. The temperature and fluid properties are assumed constant. Use fluid property data at the average temperature and pressure. Gas flow rate can be defined by either gas mole flow rate, inlet volume flow rate, mass flow rate, or inlet velocity.
General Friction Loss Calculators : Friction loss can be calculated from the DarcyWeisbach equation with the friction factor calculated from either the HagenPoiseuille Laminar flow equation, the original Colebrook White equation, the modified Colebrook White equation, the Prandtl Nikuradse smooth pipe equation, the Blasius smooth pipe equation, the Colebrook smooth pipe equation, the Miller smooth pipe equation, the Konakov smooth pipe equation, the von Karman rough pipe equation, or user defined friction factor.
