General Fluid Flow Calculators

Line Pack Calculators : Calculate fluid volume and gas line pack. Gas pipelines can be used for storage by 'packing' the pipeline, increasing the pipeline pressure and hence increasing the quantity of gas in the pipeline.

Flow Rate Calculators : Fluid flow rate can be measured by volume flow rate, mass flow rate, mole flow rate, and velocity.

Friction Factor Calculators : The Fanning friction factor is equal to the Darcy-Weisbach friction factor divided by 4. The transmission factor is equal to the inverse of the square root of the friction factor.

Average Temperature And Pressure Calculators : Pipeline temperature is assumed to decay exponentially along the length of the pipeline. The change in pressure is assumed to be proportional to the distance squared. The ambient temperature and the pipeline insulation is assumed to be constant along the length of the pipeline.

CALCULATOR Convert Darcy Friction Factor Fanning Friction Factor Darcy Transmission Factor And Fanning Transmission Factor

Convert Darcy-Weisbach friction factor, Fanning friction factor, Darcy-Weisbach 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 Darcy-Weisbach friction factor divided by 4. The transmission factor is equal to the inverse of the square root of the friction factor.

CALCULATOR Pipeline Average Gas Flowing Temperature And Pressure

Pipeline average gas 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 Pipeline Fluid Density Volume Flow Rate Mole Flow Rate Mass Flow Rate And Velocity

Pipeline fluid density and flow rate 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. Fluid flow rate (velocity, mass flow rate, volume flow rate, and gas mole flow rate) may be calculated from liquid volume flow rate, gas mole flow rate, total volume flow rate, total mass flow rate, or fluid velocity.

CALCULATOR Pipeline Fluid Quantities And Line Pack Volume

Pipeline fluid quantities and line pack volume.

Gas pipelines may be used for storage by increasing the internal pressure and hence increasing the mole volume of gas in the pipeline.

CALCULATOR Rectangular Duct Fluid Density Volume Flow Rate Mole Flow Rate Mass Flow Rate And Velocity

Rectangular duct fluid density and flow rate 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. Fluid flow rate (velocity, mass flow rate, volume flow rate, and gas mole flow rate) may be calculated from liquid volume flow rate, gas mole flow rate, total volume flow rate, total mass flow rate, or fluid velocity.

CALCULATOR Rectangular Duct Fluid Quantities

Rectangular duct fluid quantities.

Generally gas ducts may not be used for storage because of their limited internal pressure.
