A dam with water on one side has a 0.01 inch crack 10 feet below the surface of water. The length of the crack is 5 ft, and the thickness of the dam at that location is 3 ft. The water temperature is 50 degrees F. determine the following:
a) The pressure drop per unit length through the crack
b) The velocity distribution in the crack
c) The maximum velocity at the center
d) The shear stress at the wall
e) The average velocity in the crack
f) The volume now rate through the crack, in gallons per hour
g) The Reynolds number of the now based on the average velocity and crack width
