How long will it take to drain? Attn: AP Calculus teachers  could be useful in a discussion of "competing rates" problems.

How long will it take to drain? Can the water be turned on so that draining/filling balance each other out?

When will it be empty (or about empty)? Should have cut this a bit sooner...too obvious that it's going to go empty and not overflow.


How much faster does the sink drain than the faucet fills? I want to reword this.












How much water is being added? How much water is the drain removing? How long will it take to empty?


How much time does the extra lip that surrounds the entire sink, including the faucet, give you before the sink overflows?




How much do I have to put down the sink to clog it to the point that the water level stays the same (the system is in equillibrium)?

How long would the water take to drain water was not being poured into the sink?




Great video of a classic textbook problem. How long is this going to take?










Is there a vacuum cleaner inside that drain sucking water faster than it can fill?





If he turned on the hot at the same time as the cold would the sink overflow?
