WebMotor oil has greater viscosity when cold than when warm, and so pressure must be greater to pump the same amount of cold oil. Figure 5. Poiseuille’s law applies to laminar flow of an incompressible fluid of viscosity η through a tube of length l and radius r. The direction of flow is from greater to lower pressure. WebPressurize the inlet to your pump slightly [less than 15-20psi (1-1.4bar)]. This will keep the inlet tubing full and allow more efficient pumping. Decrease the viscosity of your fluid. Heat your fluid if possible, viscosity usually decreases with temperature. Selecting the proper size and type of tubing for pumping viscous fluids is an inexact ...

WebSep 12, 2024 · The direction of flow is from greater to lower pressure. Flow rate Q is directly proportional to the pressure difference p 2 − p 1, and inversely proportional to the length l of the tube and viscosity \(\eta\) of the fluid. Flow rate increases with radius by a factor of r 4. WebPitot tubes were invented by Henri Pitot in 1732 to measure the flowing velocity of fluids. Basically a differential pressure (d/p) flow meter, a pitot tube measures two pressures: the static and the total impact pressure. The static pressure is the operating pressure in the pipe, duct, or the environment, upstream to the pitot tube.

WebHere, High viscosity refers to the property of those fluids that have high internal resistance and whose viscous forces barred or interrupts the transfer of momentum that causes the flow of liquid to be too slow and sluggish.
