Two circular holes, one larger than the other, are cut in the side of a large water tank whose top is open to the atmosphere. The center of one of these holes is located twice as far beneath the surface of the water as the other. The volume flow rate of the water coming out of the holes is the same.
(a) Decide which hole is located nearest the surface of the water.
(b) Calculate the ratio of the radius of the larger hole to the radius of the smaller hole.
