Question

1. Atmospheric pressure at sea level is 76 cm of mercury. Calculate the vertical height of air
column exerting the above pressure. Assume the density of air 1.29 kgm and that of mercury is
13600 kgm? Why the height calculated by you is far less than actual height of atmosphere?

Answer 1

Step-by-step explanation:

Given Atmospheric pressure at sea level is 76 cm of mercury. Calculate the vertical height of air column exerting the above pressure. Assume the density of air 1.29 kgm and that of mercury is  13600 kgm? Why the height calculated by you is far less than actual height of atmosphere?  

• Mercury column height is 76 cm = 0.76 m
• Density of mercury ρ hg = 13,600 kg / m^3
• Density of air ρ air = 1.29 kg / m^3
• According to the question
• Pressure due to air column = pressure due to hg column
• So ρ air x h air x g = ρ hg x h hg x g
• So we need to find vertical height of air column.
• So h air = ρ hg x h hg / ρ air
•              = 13600 x 0.76 / 1.29
•            = 10336 / 1.29
•            = 8012.403 m
