(a) How high in meters must a column of water be to exert apressure equal to that of a 760 mm column of mercury? The densityof water is 1.0 g/mL, whereas that of mercury is 13.6 g/mL. answer______ m
(b) What is the pressure in atmospheres on the body of a diver ifhe is 32 ft below the surface of the waterwhen atmospheric pressure at the surface is 0.94 atm? answer________ atm
Explanation / Answer
We Know that : Pressure = density of thesubstance x acceleration due to gravity x height of the columnraised. Given : Pressure of the mercury = pressure of water 13.6 g / ml x 980 cm / s2 x 76 cm = 1 g / ml x 980 cm /s2 x h ( cm ) height of the water column raised = 1033.6 cm = 1.0336 m (b) Pressure = density of the substance x acceleration due to gravity xheight of the column raised = 1000 Kg / m3 x 9.8 m / s2 x 9.7536m = 95585.28 atm The total pressure = pressure exerted by the body of the diver +pressure at the surface of the earth = 95586.22 atm.Related Questions
