A cylindrical water-storage tank has a height of 8.3 m and a radius of 5.8 m. The storage tank is full of water but is vented to the atmosphere. The bottom of the tank is 33 m off the ground. A 14 cm diameter pipe runs vertically down from the tank and goes 1.5 m underground before turning horizontal. The water flow in the horizontal pipe is 79 L/s.

A) What is the water pressure (gauge) in the horizontal pipe underground?

B) How fast does the water level in the tank drop?

C) Rick Barnes drills a 6.1 mm diameter hole near the bottom of the tank. How fast does the water shoot out?

D) What volume flow of water is lost out the hole?
