Under normal conditions, water enters the hose at 60mmHg pressure (standard plumbing pressure in home) and a small amount of water leaks out the right end of the hose while the rest leaks across the wall of the hose. out the end Flow Region A Region B Region C Water Flow in Adjustable end cap 1. What region contains the highest pressure? 2. what region contains the lowest pressure? 3. Based on your answers, explain how direction of flow along the length of the hose is related to pressure along the length of the hose.

Explanation / Answer
