where, f is Darcy's friction factor, L is pipe length (ft), D is pipe diameter (ft), is fluid density (lb/ft³), A is pipe cross-sectional area (ft²), g is constant 32.174 ft/sec², P is pressure in psi and Ws is gas flow (lbm/sec). Subscript 1 denotes conditions at pipe inlet and 2 denotes at pipe outlet. Fluid Flow velocity in pipes, calculation and recommendation1. Introduction Why is the fluid velocity in pipes important ? The fluid velocity in a pipe is a fundamental data to calculate to be able to characterize the flow in a pipe, thanks to the Reynolds number, and size a pipe circuit calculating the pressure drop expected for a certain flow.. When designing the pipe, it is necessary to chose a fluid velocity to have good compromise in between

The gas temperature is 5 C, the surface roughness of the pipeline is 0.02 mm. Along the pipeline are 5 elbows R=1.5D, 90 deg. Pressure on the pipeline start is 2 bar gauge. Pipe Flow Calculator. Liquid or Gas Pipe Design - Pressure Since boundary conditions affect the flow characteristics, our pipe flow calculator allows you to select whether your locations 1 and 2 are within pipes, at the surface of open reservoirs, or in pressurized mains (same as pressurized tank). If there is no pump between locations 1 and 2, then enter the pump head
Pipe Flow Wizard Software - Pressure Drop Calculator The Pipe Flow Wizard software calculates pressure drop in a pipe due to friction losses and fitting losses. The pressure drop in the pipe will be affected by items such as the pipe material, internal roughness of the pipe, size of diameter, length of pipe, fluid flow rate, fluid density, and Pipe Size Estimate CalculatorPipe Size Estimate. To find your pipe size measure the circumference of the pipe with a string or a flexible tape measure. Then find the pipe size whose calculated circumference is closest to your measured circumference. Learn more about the units used on this page. Pipe Thickness Calculator As Per ASME B31.3 » The Piping This pipe thickness calculator calculates required pipe thickness for a process pipe based on ASME B31.3 Code. Detail information about behind the back calculations is given at the end of this calculator. This calculator calculates required thickness of a pipe under internal pressure based on criteria specified in section 302.1.1 and 302.2.2 of ASME B31.3 Pressure Piping 
Pipe load calculator solving for vacuum load per linear length of pipe given internal vacuum pressure and inside pipe diameter Pipe Volume CalculatorVolume of water in pipe - calculation example. Let's see how to use the pipe volume calculator correctly. For an example calculation, we need a few assumptions. We will calculate the volume of a 6-meter length pipe, with an inner diameter equal to 15 centimeters. The pipe is used to transport water. Pipe Working Pressure Calculator - Tube Tubing Working Equation:P = (2*S*T)/((O.D.-2*T)*SF) Where:P = Fluid Pressure (psi) T = Pipe Wall Thickness (in) O.D. = Pipe Outside Diameter (in) SF = Safety factor (General Calculations 1.5 10, Use 1 For Bursting Pressure)
This calc is mainly for pipes full with waterat ambient temperatureand under turbulent flow. If you know the slope rather than the pipelengthand drop, then enter "1" in "Length" and enter the slope in "Drop". If the cunduit is not a full circular pipe, but you know the hydraulic radius, then enter (Rh×4) in "Diameter".
