If I placed a upright pipe ( 20mm) in a pond of water 20ft.deep and 20ft square the water in pipe would rise?

Question

higher than the pond's level. If I drilled a small hole in the pipe just below the pipe's water level, would the water flow out of the hole for ever???

Answer 1

If the pipe is open at both ends, the air pressure would be exactly the same per sq cm inside as out. The water level might be fractionally higher in the pipe due to capillary action but the difference would be very small.

If you closed the top end of the pipe and drew out all the air you would have an aneroid barometer. You would need about 32 feet of pipe to show the difference of level due to the effect of air pressure on a column of water.

If you drilled a second hole just beneath the surface of the water, it would have no effect because the column of water supported by air pressure would be the same.

The answer is the same no matter how many times you ask the question.

Answer 2

If the pipe is higher than the level of water in the other recipient, the level of water in the pipe would rise exactly to the level of water in the recipient. Water would be at the same level everywhere, provided that the pipe has or had on open connection through which water could come inside it (when you put it in the recipient, in that instant water flushes in). So there is no point in drilling the pipe because it being under the water level means being under the level in the other recipient as well.

tricky task. try searching with yahoo or google. that could actually help!
