How far does the water have to fall

Reference no: EM13304173

Water at 20°C exits a circular tap moving straight down with a flow rate of 10.1 cm3/s.

(a) If the diameter of the tap is 1.33 cm, what is the speed of the water?

cm/s

(b) As the fluid falls from the tap, the stream of water narrows. What is the new diameter of the stream at a point 7.45 cm below the tap? Assume that the stream still has a circular cross section and neglect any effects of drag forces acting on the water.

(c) If turbulent flows are characterized by Reynolds numbers above 2300 or so, how far does the water have to fall before it becomes turbulent?
