A tank containing water and pressurized air is connected to a manometer as shown below. The listed heights are h1 = 7.6 in, h2 = 4.4 in, and h 3 = 6.8 in. If the measured barometric pressure is 14.64 psia, what is the pressure of the air in the tank? (Hints: note the units; assume the density of water is 62.4ft1bm, For the other liquids, use the values. listed in Table A-3E.)
