Q7. (25 marks) A U-tube manometer is connected to a closed tank as shown in the below figure. The air pressure in the tank is 0.5 psi (gage) and the liquid in the tank is oil (). The pressure at point A is 2 psi (gage). Determine the depth of the oil z and the differential reading h in the manometer, that is filled with a liquid having SG = 3.05 as shown in the figure as well. The manometer is open to the atmosphere and the differential reading is always measured with respect to gage pressures, i.e., take the atmospheric pressure at the open end to be 0. Given that 14.7 psi = 101,325 Pa = 1 atm and 1 ft=0.3 m. Open All 53.0
