Conclusions
The hydrodynamic theory for the undershot discharge of a straight radial gate in a conduit, in conjunction with modern computation methods and facilities, makes it possible to find the coefficients of contraction, pressure distribution, and total hydrodynamic force acting on the gate.
The results of the present investigation will lead to agreement between the experimental data where there is a maximum possible fulfillment of the requirements presented at the start of this article in regard to the flow (flow should be close to two-dimensional, the Froude number Fr = v 2∞ /gH sufficiently high, etc.).
