Air under pressure The density of the water Is p = 1000 kg/m3. The height at the top of the water is y1 = 0.077 meters, and the gauge pressure above the water is 818500 Pascals. We will treat the soda bottle a "tank\" so that the velocity of the water Inside is negligible. The radius of the opening at the end of the water bottle is r = 0.009 meters. Determine all the following: The velocity of the water at the exit of the bottle: v = m/s The mass rate of ow of the water at the exit: kg/sec The volume rate of flow of the water at the exit: [:l m3/sec
