Answer:
Altitude of the town(h1) = 1,196.8 m
Explanation:
Given:
Height of barometer(h) = 65 cm Hg = 0.65
Standard atmospheric pressure = 76 cm Hg = 0.76
Density of mercury(Pm) = 13,600 kg/m³
Density of air (Pa) = 1.25 kg/m³
Find:
Altitude of the town(h1)
Computation:
Pressure due column = Δp mercury column
(Pa)(h1) = (Pm)(h)
(1.25)(h1) = (13,600)(0.76-0.65)
(1.25)(h1) = 1,496
Altitude of the town(h1) = 1,196.8 m
