The Answer should be 2H/3. As center of pressure= H/2+{(bH^3/12)÷(bH*H/2)}=2H/3.

From the bottom it's H/3.

From the free surface of water it's 2H/3.

It's center of pressure, H/2 to surface and H/2 to bottom.

And centroid is 2H/3 below surface.

Not given that total pressure. Only center of pressure from water. Than h/2 is the right answer.

Abhinay said:   8 years ago
It's 2h/3.

Priya said:   7 years ago
It's h/3.

Ajay said:   7 years ago
Thanks for the better explanation @Akshay.

From top it should be 2/3h.

From bottom 1/3 h.

The correct Answer is H/2 because CP is always Bellow the CG.

Pressure of water acts in a triangular manner, so its answer is H/3.
