WebFlow rate and velocity are related by [latex] Q=Av [/latex] where A is the cross-sectional area of the flow and v is its average velocity. The equation of continuity states that for an incompressible fluid, the mass flowing into … Webdenotes the distance above the boundary. The fluid velocity at the boundary (y = 0) is zero. At some distance above the boundary the velocity reaches a constant value, U∞, called the free stream velocity. Between the bed and the free stream the velocity varies over the vertical coordinate. The spatial variation of velocity is called shear.
