The barometric height in a town is 65cmHg. Given that the standard atmospheric pressure
is 76cmHg and density of mercury is 13600kg/m", determine the altitude of the town. (Density of
(3mks)
air is 1.25kg/mº).​

Answer 1

Altitude of the town(h1) = 1,196.8 m

Step-by-step 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
