Velocity is the speed at which something moves in a particular direction. e.g. ...the velocity of light. 光速 e.g. ...the velocities at which the stars orbit. 恒星沿轨道运行的速度 velocity 单语例句 1. The intensity and velocity with which the world became submerged in a steep economic...
The velocity profile inside a circular pipe is well known, but if the pipe is partially filled, the problem is entirely different in the sense that the velocity distribution is significantly affected by the slope of pipe and filled water level, and so on. In order to calculate exact flow ...
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 ...
The velocity of sound in a single-phase fluid flowing in a pipe with an elastic wall shows a dependency upon the bulk modulus of the tube wall, i.e., the sonic velocity decreases with an increasing elasticity of the wall material. This behavior is reproduced in two-phase systems, where ...
Calculate the volumetric flow rate from a chosen flow velocity through a pipe or duct of a certain diameter, Q=¼vπø²
The static water pressure at point 1 in a pipe is 100 kPa, and the fluid velocity is 2 m/s. At point 2 downstream, the pipe narrows and the velocity increases to 3 m/s. What is the static pressure at that point? The usual assumptions concerning laminar flow, no friction losses, inc...
We report the formula that describes the relation between Doppler frequency shift of the emitted acoustic field and the velocity of the moving object. To verify the theory, we used a string phantom. We also tested our method by measuring fluid velocity in a tube. The results show that the ...
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. ...
An expression for the wake deficit in a turbulent flow of inelastic non-Newtonian fluids is combined with a function for the inner layer to yield a single formula for the complete velocity profile. The formula for the velocity profile has shown satisfactory agreement with experimental data for ...
1.Apply the formula to the real project, and calculate the values of the economic specific frictional resistance, optimal pipe diameter and velocity on different heating-supply scale under current prices.运用典型实例,根据市场现行价格,得出不同供热规模下的经济比摩阻值、济管径及经济流速。
