Web14. Apr. 2014 · Flow is a measure of air output in terms of volume per unit of time. The common units are litres per minute, cubic feet per minute (CFM), etc. Velocity refers to … In continuum mechanics the flow velocity in fluid dynamics, also macroscopic velocity in statistical mechanics, or drift velocity in electromagnetism, is a vector field used to mathematically describe the motion of a continuum. The length of the flow velocity vector is the flow speed and is a scalar. It is also called velocity field; when evaluated along a line, it is called a velocity profile (as in, e.g., law of the wall).

WebThis flow rate calculator uses flow velocity and cross-sectional flow area data to determine the volumetric flow rate of liquid. You can calculate the flow rate in five simple steps: Select the shape of the cross-section of the channel. Input all the measurements required to compute the cross-sectional area. Input the average velocity of the flow. Web10. Mai 2024 · If we look at it from the point of view of qualitative analysis. The relationship between the pressure in the pipe and the flow rate is proportional. That is, the higher the pressure, the higher the flow rate. The flow rate is equal to the velocity multiplied by the cross section. For any section of the pipe, the pressure comes from only one end.
