Fluid speed formula

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. WebThe speed of sound in water at 10 oC can be calculated as. c = ( (2.09 109 N/m2) / (999.7 kg/m3))1/2. = 1446 (m/s) where.
