Flow versus velocity
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). WebDec 12, 2024 · Generally used volume flow. The volumetric flow rate is equal to the cross-sectional average velocity multiplied by the cross-sectional area (the area …

In fluid dynamics, dynamic pressure (denoted by q or Q and sometimes called velocity pressure) is the quantity defined by: [1] u is the flow speed in m/s. It can be thought of as the fluid's kinetic energy per unit volume . For incompressible flow, the dynamic pressure of a fluid is the difference between its total pressure ...
WebExample - Air Flow Velocity in a Duct. The velocity in a 12 inch duct with air flow 1000 cfm can be calculated as. v i = (576 / π) (1000 cfm) / (12 in) 2) = 1273 (ft/min) Air Flow Velocity Calculator - Imperial Units. Air velocity … WebDarcy’s Law describes how head, hydraulic gradients and hydraulic conductivity are linked to quantify and describe groundwater flow. For example, to compute the discharge of groundwater ( Q) through a cross-sectional area of sand below the water table that is 100 m by 30 m ( A) with a hydraulic conductivity of 15 m/d ( K ), and with a head ...
Web5) Full Depth velocity - This is the relationship with the reported flow and the full cross-sectional area of the conduit. Note: There are separate "velocity (In)" and "velocity (out)" results for a conduit as well. These are based on the flow and flow area corresponding to the depth at the upstream and downstream node, respectively. WebSep 22, 2024 · 1038. 1482. Flow Rate (GPM) at a given velocity & line size.
