Question

In the manometer above,  point 2 is open and is exposed to the surroundings. Also, the water tank is pressurized by air from the inside as shown in the figure. If h1 = 22cm, h2 = 0.35m, and h3 = 47cm, and assuming that the acceleration due to gravity is 9.81m/s2, (density of water = 1011 g/L, density of oil = 770 kg/m3, density of mercury has a density of 13.75 kg/dm3)

 

A) Calculate the gauge pressure (in torr) of the air inside the tank.
