Question
Fluid mechanics basic conceptual MC, would you please explain why the correct answer for the first pic is a&d, and for the second one is b? please explain as detailed as possible. Thank you.
5) Given two reservoirs as follows. Select correct statement(s) (30): Horizontal force of water on arc a-b is same in magnitu Horizontal force of water on arc a-b is bigger in magnitude than that on arc c-d. de to that on arc c-d. c) Vertical force of water on arc a-b is bigger in magnitude than that on arc c-d but opposite in direction. Vertical force of water on arc a-b is same in magnitude to that on arc c-d but / opposite in direction. Vertical force of water on arc a-b is same in both magnitude and direction to that on arc c-d.Explanation / Answer
3) The force exerted by water on the bottom of containers is independent of Base area or volume of water or shape of container.
The force or pressure of water on bottom is dependent on only height of water from base. As in this case water height is same the force acting will also be same.
5) As explained above the force acting depends on height o water. In first case the curved portion is outside and in second case the curved portion is inside but still the contact area is same
So if we take resultant of force acting at some angle on curved portion it will be same as the height of water is same. Therefore the horizontal and vertical components will also be same.
