I have bad convergence using a constant velocity (v=Q/A) for a pipe inflow. Using a parabolic velocity profile I get excellent convergence! The formula is v=2*Q/A*(1-r^2/R^2) with: r - space coordinate of an axisymmetrical model R- pipe radius Does anybody know the formula of t...
6. In the electromagnetic field that countercurrent inductor produces, the metal droplet that melts gets the role suspension of electromagnetism force in quartz pipe center and had been heated up continuously. When metal droplet of melting have been heated up certain temperature surface beginning gasifi...
Flow Velocity ProfilesNot all fluid particles travel at the same velocity within a pipe. Average (Bulk) VelocityIa single average velocity to represent the velocity of all fluid at that point in the pipe. Liquid in Horizontal and Vertical Motion Equations and Calculator Compressibility of a Fluid ...
Calculate the volumetric flow rate from a chosen flow velocity through a pipe or duct of a certain diameter, Q=¼vπø²
Fibers at this range of concentration and scales play a role in the increase of viscosity. Finally, the prediction formula of velocity profile involving the effect of Reynolds number, fiber concentration, and aspect-ratio for the turbulent pipe flows of fiber suspension was derived....
Electrostatic precipitators are of two types – the dry or plate type, and the pipe of tube type wherein the collected material is removed as a dilute slurry. Efficiency of ESP is given by Deutsch-Anderson formula, which can be written as: Sign in to download full-size image 6.25. ...
To find the velocity head of water flowing in a horizontal pipe, we can use the formula for kinetic energy per unit volume, which is related to the velocity head. The velocity head (h) can be calculated using the following steps:1. Iden
The formula for the velocity profile has shown satisfactory agreement with experimental data for pipe flows. The formula is expected to be quite useful for approximate integral and differential calculation methods.doi:10.1080/03602559108019206Gorla, Rama Subba Reddy...
Experiments in Turbulent Pipe Flow with Polymer Additives at Maximum Drag Reduction In this paper we report on (two-component) LDV experiments in a fully developed turbulent pipe flow with a drag-reducing polymer (partially hydrolyzed poly......
