A legendary Dutch boy saved Holland by plugging a hole in a dike with his finger, which is 1.15 cm in diameter. (a) If the hole was 2.60 m below the surface of the North Sea (density 1030 kg/m3), what was the force on his finger? (b) If he pulled his finger out of the hole, how long would it take the released water to fill 1 acre of land to a depth of 1 ft assuming the hole remained constant in size? (A typical U.S. family of four uses 1 acre-foot of water, 1234 m3, in 1 year.)

Question
A legendary Dutch boy saved Holland by plugging a hole in a dike with his finger, which is 1.15 cm in diameter.
(a) If the hole was 2.60 m below the surface of the North Sea (density 1030 kg/m3), what was the force on his finger?
(b) If he pulled his finger out of the hole, how long would it take the released water to fill 1 acre of land to a depth of 1 ft assuming the hole remained constant in size? (A typical U.S. family of four uses 1 acre-foot of water, 1234 m3, in 1 year.)
(b) If he pulled his finger out of the hole, how long would it take the released water to fill 1 acre of land to a depth of 1 ft assuming the hole remained constant in size? (A typical U.S. family of four uses 1 acre-foot of water, 1234 m3, in 1 year.)
