Answer:
h = 287.1 m
Explanation:
the density of mercury \rho =13570 kg/m3
the atmospheric pressure at the top of the building is
[tex]p_t = \rho gh = 13570*908*0.73 = 97.08 kPa[/tex]
the atmospheric pressure at bottom
[tex]p_b = \rho gh = 13570*908*0.75 = 100.4 kPa[/tex]
[tex]\frac{w_{air}}{A} =p_b -p_t[/tex]
we have also
[tex](\rho gh)_{air} = p_b - p_t[/tex]
1.18*9.81*h = (100.4 -97.08)*10^3
h = 287.1 m
