Fluid in Motion 8th edition Serway and Uville

Answer 1

Speed of water leaving hole v = .√(2gh)

h is height of water level above hole.

v = √(2*9.81*17.0m) = 18.3 m/s

Flow rate = vA , A is area of hole

A = πd​​​​​2 /4 Hence

Flow rate = v πd​​​​​2 /4

2.8*10^-3 /60 m3 / sec = 18.3 m/s*π*d​​​​​​2/4

d = 3.25*10^-6 m = 3.25*10^-3 mm
