hi...
i have this question:
what would be the force in kilograms to press the entire volume of water from the container up the pipe at 30ft. ( some of the water will remain in the pipe of course).

anybody??

anybody?
 
Hi alibaba2! :smile:

(I assume the pipe is open at the top, so the water just spills out and disappears.)

You need to calculate the force needed to lift a 2 ft cube of water to the top of a 30 foot pipe.

So the formula you should use is … ? :smile:
 
help

no idea whatsoever...i had the formula written down,but i can't access my notes from my current location...

any help tim?

Well, what principle do you think would help … energy? … momentum? … work? … something else?

Hint: how much force is needed to raise a one-cubic-foot bucket of water a height of one foot? :smile:​
