The basic barometer can be used to measure the height of a building. If the barometric readings at the top and at the bottom of
a building are 730 and 755 mmHg, respectively, determine the height of the building. Assume an average air density of 1.18 kg/m^3.
1 answer:
Answer:
h = 287.1 m
Explanation:
the density of mercury \rho =13570 kg/m3
the atmospheric pressure at the top of the building is

the atmospheric pressure at bottom


we have also

1.18*9.81*h = (100.4 -97.08)*10^3
h = 287.1 m
