Question

Write down the expressions of pressure at a point ℎ below the surface of liquid of density ݀.​

Answer 1

Answer:

mgh + P (liquid pressure plus atmospheric pressure)

Answer 2

Centre of pressure may be defined as ‘the point in a plane at which the total fluid thrust can be said to be acting normal to that plane’.  the hydrostatic pressure exerted by a liquid of density ρ or specific weight w, at depth h below the surface, is: = ℎ= ℎ
