Lab 2 - Center of Pressure

Question 1

Purpose

Answer 1

To determine the center of pressure for a fully and partially submerged plane area of defined depth

Question 2

What happens to pressure in the situation where the surface is horizontal or parallel to the fluid surface?

Answer 2

the pressure over the entire area is uniform because the depth is the same throughout. The total force would simply be the unit pressure multiplied by the entire area and would act vertically at the centroid of the area

Question 3

where does the line of action of the resultant force have its piercing point?

Answer 3

on the surface at a point called the center of pressure, with coordinates ycp and zcp.

Question 4

Apparatus

Answer 4

P6237 Center of Pressure Apparatus

Question 5

The fabricated toroidal quadrant has dimensions:

Answer 5

100 mm internal radius, 200 mm outer radius

and 75 mm width
