Atmospheric 2901

The measured value of atmospheric pressure is 96,000 Pa. We want to verify this value with a closed tube at one end. Before measuring, fill the tube with glycerol (density of glycerol ρ = 1200 kg/m3). How long does the tube have to be?

Correct answer:

x =  8.1549 m

Step-by-step explanation:

p=96000 Pa ρ=1200 kg/m3 g=9.81 m/s2   p = ρ g x  x=p/(ρ g)=96000/(1200 9.81)=8.1549 m
