How much is the cross sectional area for the tube to fill up the compartment?

[aiklone1314]

Homework Statement

abstract question, but we can assume the
volume,V to be filled is 0.0001m3 and
time for it to filled up water is 60seconds,
water density is 1000kg/m3,
so how much should be the cross sectional area,A for the tube?

Homework Equations

Volume flow rate=delta Volume/delta time
Volume flow rate= cross sectional area*velocity of water

Relavant Picture:
When 0.0001m3 of water is filled up in the compartment, the compartment of the verge will move downward as shown in the rightside of the picture.

You need an equation for how flow rate depends on length of tube, cross-sectional area of tube, pressure difference along the tube and properties of the fluid. See what you can find online.

So is this equation is needed to be used?

Volume flow rate= cross sectional area*velocity of water

That's one equation, but it doesn't mention pipe length or pressure difference.
The subject is complicated in general by the question of whether the flow it turbulent or laminar.
Search online for Bernoulli's equation and try these:
