Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFExplanation:
Centre of pressure:
- It is the point of application of total pressure on the surface when the fluid comes in contact with a plane or curved surface.
Centroid:
- Centroid is known as geometrical center or center of figure of a plane figure or solid figure.
Centre of gravity:
- It is imaginary point in a body where total weight of the body is thought to be concentrated.
Important Points
Centre of pressure for a body placed vertically inside a fluid can be determined as: \(h^{\ast }=\overline{h}+\frac{I_{c.g}sin^{2}\theta }{A\overline{h}}\) ,
where Ic.g = Moment of inetria about centroidal axis, \(\overline{h}\) = C.G from liquid surface
