Asiphon is a tube that exploits bernoulli's equation to move fluid around obstacles, to a lower elevation. one siphon is 2 cm in diameter and transfers fluid from a large reservoir to a 50 l bucket 2 m below the sur- face ofthe reservoir. the siphon travels upward initially, 20 cm above the reservoir surface, then downward to the bucket. along the tube, there is a pinhole at 10 cm below the reservoir's surface level. determine: (a) how long it takes to fill the bucket. (b) if water leaks out or air is drawn in at the pinhole. (c) if the uppermost bend in the siphon is safe from cavitation.
