The equation for pipe diameter is the square root of 4 times the flow rate divided by pi times velocity. For example, given a flow rate of 1,000 inches per second and a velocity of 40 cubic inches per second, the diameter would be the square root of 1000 times 4 divided by 3.14 tim...
Pipe Diameter:A larger diameter allows for a higher flow rate, reducing pressure drop and fluid resistance. Pipe Length:Longer pipes increase the resistance and reduce the flow rate, necessitating more powerful pumps. Pipe Material:Roughness and corrosion resistance of the pipe material can impact th...
Physicists and engineers use Poiseuille's law to predict the velocity of water through a pipe. This relationship is based on the assumption that the flow is laminar, which is an idealization that's more applicable to small capillaries than to water pipes. Turbulence is almost always a factor ...
Laminar flow in circular tubes with parabolic velocity distribution is known asPoiseuille flow. This special case is found frequently in vacuum technology. Viscous flow will generally be found where themolecules’ mean free pathis considerably shorter than the diameter of the pipe: λ «...

However, with compressible fluids (gases and vapors), density, and hence velocity, may change considerably from one end of the pipe to the other. This, along with the limitations imposed by choked flow, ...
Calculate the volumetric flow rate of water for the pipe shown. Answer: Q = 2.46 x 10-5 m3 / s Volumetric flow rate for incompressible fluids is {eq}Q=A_1v_1=A_2v_2 {/eq} Bernoulli's equation is given by {eq}\frac{p_1}{\rho g}+\frac{v_1^2}{...
due to the friction between the fluid and the pipe wall and internal friction within the fluid. The Darcy Weisbach Equation, which will be discussed in this article, is commonly used for a variety of calculations involving frictional head loss, pipe diameter, f...
Yes, flow is sub sonic and compressible. At glance I don’t see any problem with BC. But not clear about initialization. Would recommend you initialize the domain only with U-velocity of 200 m/s and fix the time step based on the residence time/10 (diffuser length , inlet velocity). ...
Equation of Continuity: The equation of continuity essentially states that the volume flow rate of an incompressible liquid through a pipe must be constant at all points in the pipe. Thus, the product of the area and the flow velocity at any given point must be constant. Therefore, the ...
