Unformatted text preview: Exam 16 3-3 Measuring Pressure with a Multiﬂuid Manometer The water in a tank is pressurized by air, and the pressure is measured by a multiﬂuid manometer as shown. The tank 3 L is located on a mountain at an altitude of 1400 m where the atmospheric pressure is 85.6 kPa. Determine the air pressure in the tank ifhl = 0.1 m, I12 = 0.2 m, and h3 = ' 0.35 Hi. Take the densities of water, oil, and mercury to be 1000 kg/mj, 850 kg/rn3, 1. and 13,600 kg/m“, respectively. T Mercury SOLUTION The air pressure in the tank is to be determined. Assumption Neglect the variation in air pressure in the tank with elevation due to its low density. Properties The densities of water, oil, and mercury to be 1000 kg/ma, 850 kg/m3, and 13,600 kg/m3, respectively. Analysis ”Deg“ '3 (@Oa'gv «CySll‘Ew-q “l"ZT ( Orlﬁta 1‘5 av‘oi‘i‘farz) 6mm; MA Mac-J.
