The barometric pressure at sea level is 760 mm of Mercury while that on a mountain top is 715 mm. If the density of air is assumed constant at 1.2 kg/m^3 , what is the elevation of the mountain top?
(a) 510 m
(b) 1020 m
(c) 255 m
(d) 128 m
The question was posed to me in an online quiz.
This interesting question is from Pressure at a Point in Compressible Fluid in chapter Pressure and Its Measurement of Fluid Mechanics
