The barometer in a city was found to be 70 cmHg. Given that the standard atmospheric pressure is 75 cmHg and the density of mercury is 13600kg/m^3, determine the altitude of the city. (density of air is 125kg/m^3)

Answers

Air column = altitude of the place
Pressure due air column = pressure difference of the mercury column
pahag = pmhmg
125 x ha x10 = 13600x10 (75-70)/100
1250ha =13600x10x5/100
Ha=5.44m
