Question

Determine the atmospheric pressure at a location where the barometric reading is 745 mmHg. Take the specific gravity of mercury to be 13.6.

Answer 1

Answer:

Explanation:

Given

Barometric reading $h_{g}=754\ mm\ of\ Hg$

The above value is pressure head, so converting into Pressure

$P=\rho \times g\times h$

where $\rho =$density of mercury

g=acceleration due to gravity

h=height

$P=13.6\times 10^3\times 9.8\times 0.754$

$P=100.49\ kPa$
