Answer:
v = 40 m/s
Explanation:
Difference in the height of the two columns:
[tex]h_m = \triangle h = 10 cm \\h_m = 0.1 m[/tex]
Air density, [tex]\rho_{air} = 1.225 kg/m^3[/tex]
Water density, [tex]\rho_{w} = 1000 kg/m^3[/tex]
The velocity of air flow is given by the equation:
[tex]v = \sqrt{2gh_m (\frac{p_w}{p_{air}} - 1) } \\\\v = \sqrt{2*9.81*0.1 (\frac{1000}{1.225} - 1) }\\\\v = 40 m/s[/tex]
