If a container has 1 liter of water in it, how big the hole at the bottom is if it takes 24h for it to drip out?
>>
the size of your mums anus

need the height of the container to solve it
>>
>>8080589
We assume the containers a perfect cube
>>
>>8080606
still need the height
>>
>>8080608
*sigh* 10cm

>>8080448
What is the local gravity?

well we know flow rate = velocity x area

we got flow rate 1L/24hrs = 1.572e-8 m3/s

we get velocity from bernoulis principle

[(v1)^2]/2 + gz1 + P1/p1 = [(v2)^2]/2 + gz2 + P2/p2

v = velocity
g = gravity
z = height
P = pressure
p = density

we take reference point 1 as top of container

so v1 = 0 since water at top is pretty much not moving, P1 = P2 = atmospheric pressure, p1 = p2 since incompressible fluid, z2 = 0, z1 = 0.1m

so final eq is

gz1 = [(v2)^2]/2

v2 = 1.401 m/s

so area of hole = q/v = 1.122e-8 m2

hole radius = (area/pi)^(1/2) = 5.976e-5 m

4 light years.

>>8080608
No you don't. The size of the hole is dependent on the side lengths of the cube.

level?
closed container?
pressure loss negligible?
speed of fluid IN container negligible?
aperture level?
shape of aperture?
spin flow in aperture?
referring to Oh*Re >= const. ?
