Introduction:

Hydrostatic pressure varies only with the vertical distance and is independent of the shape of the container. Thus, the pressure increases with depth in fluid. In this experiment we will investigate the resultant hydrostatic force applied on a submerged surface (the rectangular surface of Toroid ). Plus, determining the center of pressure experimentally and theoretically.

Experimental Procedures:

1. Leveling the Flotation Tank

2. Adjusting the counterbalance weight. (leveling the balance arm) 3. Initial filling of the floatation tank.

4. Adding weight.

5. Filling the tank to rebalance the added weight. (re leveling the balance arm) 6. Measuring the water level.

7. Draining the...
