Problem four (30 points) The U-tube manometer is used to measure the pressure PA in a vessel containing a liquid density of pA = 1 g/cm? Calculate the pressure PA in Pa and Psi, if PB = 13.6 g/cm, h= 0.5 m and hz = 2.50 m. Patm = 101325 Pa Fluid density P Manere identity A U-Tube manometer Problem five (40 points) The water in a tank is pressurized by air, and the pressure is measured by a multifluid manometer as shown in Figure below. Determine the gage pressure of air in the tank if h = 0.66 ft, h2 = 30 cm, and h3 = 18.1 m. Take the specific gravities of water, oil, and mercury to be 1, 0.85, and 13.600, respectively
