An aircraft cruises at an altitude of 10,700 meters above sea level. estimate the atmospheric pressure in bar at cruise altitude. assume the acceleration of gravity is constant at g = 9.8 m/s. the average specific volume of the air is 1.334 m /kg. (ans. 0.227 bar) 1.7 a vacuum gage attached to a power plant condenser gives a reading of 27.86 in. of mercury. the surrounding atmospheric pressure is 14.66 lbf/in. determine the absolute pressure inside the condenser, in lbf/in.? the density of mercury is 848 lb/ft and the acceleration of gravity is g = 32.0 fts? (ans. 1.07 lbf/in.) 1.8 a glass tube is attached to a pipe carrying water as shown in fig. p1.8. the pressure of water in the pipe supports a column of water 2 ft. high. if the atmospheric pressure is 14.42 lbf/ determine the absolute pressure of the water at the bottom of the tube, in ibf/in.? the specific volume of water is 0.0164 ft /b, and the acceleration of gravity is 8 = 32.2 ft/s.
