A student goes to the laboratory supply room and obtains six feet of clear plastic tubing with an outer diameter of 12mm and a wall thickness of 2mm. She bends the tube into a U shape with the open ends pointing up and uses a funnel to pour 75mL of water into the tube. By blowing air into one end of the tube, she generates a 5.00-inch difference in the water levelson each side. Pressure Exerted What was the pressure (atm ) she exerted with her lungs on the water in the tube? Consider all assumptions explicitly. atm eTextbook and Media Attempts: 0 of 10 used Alternate Fluid If the fluid had been carbon tetrachloride instead of water and the student had exerted the same pressure. what would the difference in the liquid levels have been? inch
