Oh Hi there, can you help me real quick please? Thanks :)
About the path of water coming from each hole:
The path of the water is a section of a parabola, the same as for any projectile. Compared to the others, the water from the top hole curves toward the ground most quickly. The water from the bottom hole curves toward the ground least quickly.
water pressure increases with depth , this was what i learnt last year in 9th grade . The same is the reason why water flows faster from the hile located at the bottom .
Same is the reason why bottom of dams are made thicker .
Pressure = depth × g × density .
where g is the acceleration due to gravity and density is mass/volume
hope it helps you
