CALCULATOR MODULE : Liquid Pipeline Pressure Loss From The Darcy Weisbach Equation ±
Calculate single phase liquid pipeline pressure loss using the Darcy Weisbach equation. `Po = P - (fd L / (ID) + K) 1/2 ρ V^2 + ρ g (zi - zo) ` where : Po = outlet pressure
P = inlet pressure
fd = Darcy friction factor
L = piping length
ID = piping inside diameter
K = total friction loss factor for fittings
ρ = fluid density
V = fluid velocity
g = gravity constant
zi = inlet elevation
zo = outlet elevation The Darcy friction factor can be calculated for - Hagen-Poiseuille laminar flow equation
- original Colebrook White equation
- modified Colebrook White equation
- Prandtl Nikuradse smooth pipe equation
- Blasius smooth pipe equation
- Colebrook smooth pipe equation
- Miller smooth pipe equation
- Konakov smooth pipe equation
- Von Karman rough pipe equation
For low Reynolds numbers Re < 2000, the fluid flow is laminar and the Darcy friction factor should be calculated using the Hagen-Poiseuille laminar flow equation. For high Reynolds numbers Re > 4000, the fluid flow is turbulent and the Darcy friction factor should be calculated using one of the turbulent flow equations. In the transition region 2000 < Re < 4000, the flow is unstable and the friction loss cannot be reliably calculated. The minor loss K factor is used to account for pipeline fittings such as bends, tees, valves etc.. The calculators use the Darcy-Weisbach pressure loss equation. The Fanning friction factor is used with the Fanning pressure loss equation. The transmission factors are commonly used for gas flow. The results for the Darcy and Fanning equations are identical provided that the correct friction factor is used. Change Module : Related Modules : |
CALCULATOR MODULE : Liquid Pipeline Fluid Density Viscosity And Specific Gravity ±
Calculate single phase liquid density, specific gravity, degrees Baume, degrees Twaddell, and degrees API. For liquids lighter than or equal to water the density can be defined as degrees API, or degrees Baume minus (Be-). For liquids heavier than water the density can be defined by degrees Baume plus (Be+), or degrees Twaddell. Change Module : Related Modules : |
CALCULATOR MODULE : Compressible Flow Speed Of Sound ±
Calculate gas and liquid speed of sound and Mach number. The Mach number is the ratio of the flow velocity to the speed of sound. It applies to either a moving fluid or to a moving object passing through stationary fluid. For a Mach number greater than one, the flow is supersonic. For a Mach number less than one, the flow is subsonic. For an ideal gas, the speed of sound or sonic velocity can be calculated from the gas temperature, gas specific heat ratio and the gas specific gravity. For liquids the speed of sound can be calculated from the liquid bulk modulus and the liquid density. Reference : Fluid Mechanics, Frank M White, McGraw Hill Change Module : Related Modules : |

CALCULATOR MODULE : Fluid Density And Volume ±
Calculate fluid density for single phase fluid (oil, water, or gas), two phase fluid (oil and gas, or oil and water), and three phase black oil (oil, water and gas). The gas oil ratio is the ratio of gas moles to oil volume. Gas oil ratio is often measured as gas standard volume (scf or scm) per oil volume (barrels, gallons, cubic feet or cubic meters). The gas mass fraction is the ratio of gas mass to total fluid mass. The gas volume fraction is the ratio of gas volume to total fluid volume. Water cut is the ratio of water volume over total liquid volume (equals the water volume fraction in the liquid). Gas volume is dependent on fluid temperature and pressure.
