The water supply of a 36-story building is fed through a main 8-centimeter diameter pipe. a 1.6-centimeter diameter faucet tap located 22 meters above the main pipe is observed to fill a 30-liter container in 20 seconds. what is the speed at which the water leaves the faucet?
Assuming the water leaves the facet with a speed
So, we have an equation with one unknown
Solution of this linear equation (speed the water leaves the facet in m/sec) is
Personally, I think that this is a very high speed and the numbers in this problem might not be practical.
