AI Thread Summary
To calculate the force required to press the entire volume of water from a container up a 30-foot vertical pipe, one must consider the weight of the water being lifted. The discussion suggests using principles of energy, momentum, or work to derive the necessary formula. A key hint provided is to determine the force needed to raise a one-cubic-foot bucket of water one foot high. The participants are seeking clarity on the calculations involved, particularly regarding the volume of water that will remain in the pipe. Understanding these principles is essential for accurately determining the force in kilograms needed for the task.

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).

BIG thank you

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:​
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
