Heavy rains have flooded your professor's basement to a depth of 6 cm. This basement is 12 m by 10 m in area. You have a hose of diameter 1.7 cm and can run the hose from the water in the basement to a level 2.3 m below the level of the basement floor, into a low low portion of the yard. When the hose is filled with water, it acts as a siphon and empties the basement.
a. What is the speed of the stream of water leaving the hose?
b. Approximately how long does it take to empty the basement?
