For rectangular, the Area = A x B. volume = L * (b1 + (b2 - b1) * h1 / h + b1) * h1 / 2. Flumes are static in nature - having no moving parts - and develop a relationship between the water level in the flume and the flow rate by restricting the flow of water in a variety of ways. Already in the precast concrete plant of Klebl, the channels with inserted foam filling are set in concrete to be flush with the surface and in alignment. This method combines mass conservation with the simplest possible treatment of momentum conservation, namely that all terms in the general momentum equation (pressure gradient, local acceleration and convective acceleration) are. In trapezoidal and parabolic channels, the governing equations are highly nonlinear in the normal and critical flow depths and thus solution of the implicit equations involves numerical methods (except for critical depth in parabolic channels).
