"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 for a closed conduit P = 2(h+w). As a general rule, open channel flow is laminar if the Reynolds number defined by the hydraulic radius, Re = URh/ν is less than 500. As the " - Flow rate hydraulic definition
