The discharging capacity is controlled by a rotary flow generator and the barrage size,the influence of the barrage aperture on discharge is obvious,but the effect o.

This paper analyzed and compared the common tap effluent phenomena, functioning waterhead, discharging capacity in the hydrotechnics according to calculation theories of pipe outlet, showing significance of pine outlet in practical application.

Based on Tibet Laluo Hydroproject and Irrigation Project,some methods in common use are adopted to calculate the eco-environment water demand and contrast with the discharged flow which the project study out.

This paper deals with the calculating method—time-average discharge method on the surge and discharges with non-uniform flow state in the flood period or under the suddenly losing of power load, which was based on a hydraulic model test of the power canal.

In order to determine the elevations of the structures in the canal system,the surge heights and discharges must be calculated.

On the basis of the long time change of fundamental component of leakage current on composite insulators, by using several optimal linear equations to simulate wettability process, the authors firstly summarized the mathematic models to describe the wetting process of composite insulators.
