We subtract weight W since the shaded volume is below the curved surface. It turns out that for cylindrical surfaces (a circular arc shape), the resultant hydrostatic force acting on the surface always passes through the center of the circular arc.
#055 Designing the Tip Shape of Pin Point Gate
These are the problems that a mold designer has to solve whenever adopting a pin point gate. Some technical measures for solving these problems are described below. Fig. 1 shows the structure of a general pin point gate. This is the shape when the gate design is made without any special considerations.

Resultant hydrostatic force on a gate for a fluid that doesn’t reach ...
2021年10月11日 · 1. Assume the water has reached the mid-height of the gate, below that is the mercury. Then the upper half of the gate is subjected to water pressure. Once the pressure diagram is drawn, you can find the force by integrating the respective pressure over the half-circle and find the force center.
