WebOpen-Channel Flow The calculator computes ratios to free stream values across an oblique shock wave, turn angle, wave angle and associated Mach numbers (normal components, M n , of the upstream). Input M 1 value and select an input variable by using the choice button and then type in the value of the selected variable. WebThe velocity distribution coefficient is taken to have a value of one for turbulent flow in prismatic channels but may be significantly different than one in natural channels. 7.4.3 Velocity Distribution Coefficient Due to the presence of a free surface and also due to friction along the channel boundary, the

WebThe characteristic length-scale for a channel of width w and depth h is the hydraulic radius, Rh = wh/P, where P is the wetted perimeter. For an open channel P = (2h + w) and ... 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.
