Given the dimensions in the figure above, and the following data:

Water Temperature: 21.6 degrees celsius

(Depth = Depth of the water in each trial and there was seven trials)

(Mass = Mass of each trial needed to equalize the beam)

1. Compare the theoretical force with the measured force. The measured force is obtained by setting the summation of moments about the pivot point equals to zero. However, the calculation involved the assumption that the center of pressure can be calculated from the equation provided below.

2. Also confirm that if depth is less than 100mm, the center of pressure is located h/3 from the bottom of the quadrant(h=depth of water). Explain why the center of pressure is NOT located at a distance h/3 from the bottom of the quadrant for depths greater than 100mm.
