Homework Statement A solid sphere and a hollow sphere of same radius and same material are dropped from the top of a beaker filled with water. The height of water in the beaker is 'H'. Which sphere will reach the bottom of the beaker earlier and why? (Neglect any viscous force)

Ok, I've come across this problem in fluid statics, but seem to be getting the integration wrong: "A semicircular plane is submerged vertically in a homogeneous liquid with its diameter d at the free surface. At what depth s is the centre of pressure?" The answer should be s = (3*pi*d)...

When finding the force required to hold the dish in place, do I have to take account for both of the "jets" going out from center? I mean, there will be two forces in the negative x direction because of the water jet right? I hope the question is clear enough :redface:

A swimming pool has dimension 23.0 m by 8.0 m with a depth of 3.0 m. When it is filled with water, what is the force (resulting from the water alone) on the bottom? When it is filled with water, what is the force (resulting from the water alone) on each short side? i figured out part a...

Vibrations and Fluid Statics One end of a horizonatal wire is fixed, while the other passes over a smooth pulley and has a heavy weight attached to it. The frequency of the fundamental note emitted when the wire is plucked is 392 Hz. When the weight is completely immersed in water, the new...

I am a newbie to fluid mechanics, and I am confused about the "hydrostatic paradox". To begin with, consider three containers. All three have the same base area (all circular), but the angle between the base and the "wall" are all different: Container 1: obtuse angle Container 2: right angle...
