Question

how to draw water and oil projection which there are 2 containers and have hole at the same level?

Answer 1

Let the density of the water is $\rho$ and density of the oil is $\sigma$

Let the height of the hole from the ground is h,

Then $v^2=u^2+2gh$

here initial velocity in the horizontal direction = 0

$v = \sqrt{2gh}$

Both will have the same velocity at just before hitting the ground.

Applying the bernaull's equation,

$\rho g (H-h)=\frac{1}{2}\rho v^2$

So, it is not depending on the density of liquid.
