The force "F" exerted by a fluid of constant weight density "w" against a submerged vertical plane region from y=c and d.
F=w^{d}_{c} h (y)×L (y) dy
What is fluid force?
The pressure on an object at a certain depth "h" in a fluid is p=wh where "w" is the weight density of the liquid per unit volume.
What is Pascal's principle?
The pressure exerted by a fluid at a depth "h" is transmitted equally in all directions. P=f/a or force/area
What is the weight densities of water and sea water?
Water=62.4 sea water=64.0
Does the size of the body of water effect the fluid force?
No.
What is the moment of center of mass for one dimension?
Let point masses be m_{n }located at x_{n }. The moment about the origin is M_{o }= m_{1}x_{1 }+ m_{2}x_{2 }+...+ m_{n}x_{n}. The center of mass is =M_{o }/m
What is the center of mass for 2 dimensions?
The point masses are m_{n }located at (x_{n }, y_{n }). The moment about the y-axis is m_{y }= +...+m_{n}_{ }x_{n . }The moment about the x-axis is m_{x}= +...+m_{n }y_{n }. The center of mass is (,) where =M_{y }/m and =M_{x }/m.
What is the moment and center of mass of a planar lamina?
f (x) g (x), on [a, b]. The planar lamina of uniform density is "p" bounded by the graphs.
