| Abstract: | The continuity equation and the energy equation are applied to investigation of the theory of hydraulic computation of movable weir. And theory of boundary layer is applied to illustrating the head loss of water flowing through movable weirs. Then it is programmed in Fortran language. Experiment and analysis of movable weir for flow measurement indicate that the modular limit of movable weir is relatively high. And the accuracy of theoretical discharge calculated is satisfied. |
