Fluid speed formula
WebA1v1 = A2v2 Solving for v2 gives you the following: Now plug in the numbers. Because the doctors told you A2 = 2.0 A1 and you know that v1 = 0.4 m/s, you get So now you’re ready to work with the equation you derived: You can factor out both 1/2 and the density, on the right side of the equation: Plugging in the numbers gives you the following: WebThe flow velocity formula used by this calculator is: v = Q / (π · (ø / 2)²) Derived from: v = Q / A A = π · r² r = ø / 2 Symbols Q = Volume flow rate v = Flow velocity A = Cross-sectional area r = Radius ø = Diameter n.b.

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.
