Flow rate stream function

WebThe strength of a sink is given by the volume flow rate of the fluid it absorbs. Types of two-dimensional flows Uniform source flow. A radially symmetrical flow field directed outwards from a common point is called a source flow. The central common point is the line source described above. ... The stream function associated with sink flow is – Web6 over the bed at different flow speeds. He found two different behaviors defined by the roughness Reynolds number, εu*/ν.For conditions with εu*/ν < 5, yo = ν/9u*, i.e., the characteristic roughness is NOT a function of the real roughness scale.
