Amercury manometer (rho = 13,600 kg/m3) is connected to an air duct to measure the pressure inside. the difference in the manometer levels is 30 mm, and the atmospheric pressure is 100 kpa. (a) judging from fig. p1–65, determine if the pres- sure in the duct is above or below the atmospheric pressure. (b) determine the absolute pressure in the duct

Assume that a person skiing high in the mountains at an altitude of h = 15100 ft takes in the same volume of air with each breath as she does while walking at sea level. determine the ratio of the mass of oxygen inhaled for each breath at this high altitude compared to that at sea level. assume that the air composition (i.e. % of air that is oxygen) is the same at sea level as it is at 15100 ft.
