Abstract The purpose of this experiment was to determine the relationship of the center of pressure and a surface’s equilibrium of moment. The center of pressure was found using the same method for several trials. As a general conclusion, we determined that the center of pressure can be easily found based on certain assumptions for the procedure.

10) Introduction The purpose of the experiment was to demonstrate the principles of fluid statics on submerged bodies. The experiment was also conducted to determine the resultant force and location of the center of pressure for a partially and fully submerged planar surface. By using the given equations for the plane classification, we were able to calculate the resultant forces and moments. The experiment was divided into two primary sections for a better determination of the forces; these were the partially and the fully submerged cases.
Theory The study of fluid mechanics involves both dynamics and statics. This experiment dealt with fluid statics, particularly the determination of the center of pressure. The center of pressure is a point where the resultant hydrostatic pressure is acting on the plane. Pascal's law states that if a body of fluid is in static equilibrium then the pressure is uniform over any connected horizontal planar surface lying entirely within the fluid. Some assumptions were that the density of the fluid remains constant, regardless of the pressure changes and the temperature remains constant as well as the gravitational acceleration. We can use the following equations to find the resultant force. h R R B R R B M TH ) ( 2 ) ( 3 ) cos ( 2 1 2 2 3 1 3 2 (1) Where γ is the weight density and B is the breadth of the quadrant.
