WebJul 18, 2024 · Stream function. A streamline at time t is defined as the curve whose tangent is everywhere parallel to the velocity vector. With dx along the tangent, we have. u × dx = 0. and with u = (u, v, w) and dx = (dx, dy, dz), the cross product yields the three equations. vdz = wdy, udz = wdx, udy = vdx. or equivalently,
WebFeb 24, 2024 · In the late 19th century, an accountant-turned-engineer named Robert Manning developed an equation that describes the effects of a channel's characteristics on an open channel's water flow rate.
