Water falling vertically from the mouth of a tap in a streamline flow forms a tapering column as shown in the figure. Which of the following is the most correct explanation for this?

Water is flowing through a pipe of uniform cross-section under constant pressure. At some place, the pipe becomes narrow. The pressure of water at that place

Pressure applied to an enclosed fluid is transmitted undiminished to every portion of the fluid and the walls of the containing vessel. This law was first formulated by
