This calculates the sonic velocity of a specified gas flowing in a pipe. Sonic velocity is also known as speed of sound. This is mainly the sound velocity of the internal substance in a pipe. This mainly targets process and chemical engineers whom may find it

A: For underground installations, 20 m/s is normal. Maximum velocity in a pipeline, on the other hand, is defined by available pressure, but in control and safety valves, it can be allowed up to 100 m/s. Q: Thanks for the information.
The Basics on How Fluid Flows in Pipes A fluid is either a liquid or a gas. In industry they are piped from storage to the point of use. Correct design and installation of the piping system minimises pressure loss and improves the behaviour of equipment and
T = temperature of gas flow R; R = (FT3 * psia / lb mole * R). The recommended values for the velocity of gas main transmission lines is usually 40% to 50% of the erosional velocity (10 13 Ejm value d m / sec or 33 43 ft / sec is an acceptable value for
10/9/2002 Maximum velocity is a frequent topic on these forums. There must be some widely varying assumptions to get the range of nuers that I''ve seen here. For "dry gas" flow I use an actual velocity (as opposed to "velocity" calculated as SCF/FlowArea) of 100 ft Puhui Pipe manufacturer in China
Example #16 Task: Calculate the pressure drop generated by the natural gas at a flow rate of 200 Sm3/h through a pipe with nominal diameter of 2 inch and a length of 200 m. The gas temperature is 5 C, the surface roughness of Puhui Pipe manufacturer in China
4/5/2011 Thanks for the information. I noticed from the pipeflowcalc, for 2inch pipe with 1,500 feet length, 90 psi in and 10 psi drop, it gives a result of 337 cfm gas flow with a 44 and 50 fps velocity. But shouldnt the velocity of this be 257fps (based on that 337cfm flow and Puhui Pipe manufacturer in China
16/2/2006 I am designing new piping header for a Natural gas piping. The pressures are around 50 psig and the flow is around 20 MMSCF/D of 0.6 SG NG.

VVR 120 Fluid Mechanics PIPE FLOW Flow of water, oil and gas in pipes is of immense importance in civil engineering: • Distribution of water from source to consumers (private, municipal, process industries) • Transport of waste water and storm water to recipient
Flow Rate and Pressure Drop of Natural Gas Through a Pipeline There are several formulas to calculate the flow rate and some considerations should be taken for the proper use of them: They are empirical, meaning that many elements on them are constants or values that are valid within a certain set of units and should be changed when considering another set of units.

Generally, for a particle size of 1 micron to remain entrained, the gas velocity should be in the range of 2.5 to 4.5 m/s, depending on the pipe size. Measures to prevent low velocities In intermittent or batch transfer operations, when demand is low at the receiving station, continue pumping at the same high rate as required for peak demand but for a shorter duration.
Shan238: API RP 14E recommends as a criteria to size gas pipelines, that velocity of gas shouldn''t be over 60 ft/s, thus to keep the levels of noise to a minimun, that''s not an absolute criteria but I think you can use it to estimate the diameter of the branch, using the above equation, seting the velocity at 60 ft/s and knowing the flow that you''re going to transport tru the branch you''ll get the minimun diameter
