WebNov 11, 2012 · A flow in which quantity of liquid flowing per second is not constant, is called unsteady flow. Unsteady flow is a transient phenomenon. It may be in time become … WebVelocity fields. Consider the velocity vector field v v of a steady-state fluid flow. The vector v(x,y) v ( x, y) measures the instantaneous velocity of the fluid particles (molecules or atoms) as they pass through the point (x,y) ( x, y). Steady-state means that the velocity at a point (x,y) ( x, y) does not vary in time -even though the ...

WebWhat is an example of steady flow? Some examples of steady-flow devices include pipes, nozzles, diffusers, and pumps. Generally, the material flowing through the device is a gas or liquid, and if the device in any way changes the velocity of the fluid then that fluid will exert a force on the steady flow device in return. WebSteady Flow. The flow is steady when the velocity of every particle within the fluid is constant in time. However, this statement does not mean that the velocity of fluid particles will not vary at a different point in space. ... The …
