A tank with an attached manometer contains water at 20. The atmospheric pressure is 100. There is a stopcock located 1 from the surface of the water in the manometer. The stopcock is closed, trapping the air in the manometer, and water is added to the tank to the level of the stopcock. Determine the increase in elevation of the water in the manometer assuming the air in the manometer is compressed isothermally.
