Question

Question 4. The continuity equation is a statement of mass conservation that the volume flow rate Q must be constant, so we can write Q = A1v1 = A2v2 where

A is the flow cross-section area and v is the fluid speed.According to the continuity equation, how should the speed of the flow at the hole at the bottom compare to the speed of flow at the top of the cup? Note that the area of the hole and the circular area of the cup are the appropriate cross-sections to use.
