Water is draining from an open conical funnel at the same rate at which it is entering at the top. The diameter of the funnel is 1 cm at the top and 0.5 cm at the bottom, and it is 5 cm high. The friction loss in the funnel per unit mass of fluid is given by 0.4v2, where V is the velocity leaving the funnel. What is (a) the volumetric flow rate of the water and (b) the value of the Reynolds number entering and leaving the funnel. (c) How does the result of part c affect any assumptions you made? water V 1 D = 1 cm h=5 cm D2 = 0.5 cm 2 V2
