Question

One of the dangers of tornados and hurricanes is the rapid drop in air pressure that is associated with such storms. Assume that the air pressure inside of a sealed house is 1.02 atm when a hurricane hits. The hurricane rapidly decreases the external air pressure to.910 atm. What net force (directed outwards) is exerted on a 2.02-msquare window on the house

Answer 1

Answer:

Force = 22508.86 N

Explanation:

Given:

Area of the window, A = 2.02 m²

Air pressure inside the house, P₁ = 1.02 atm

External air pressure, P₂ = 0.910 atm

Now, The difference in the pressure, ΔP = P₁ - P₂ = 1.02 - 0.910 = 0.11 atm

or

ΔP = 0.11 atm  ×  (101300 Pa / 1 atm )

ΔP = 11143 Pascals

Now,

the Force is given as:

Force = Pressure × area

on substituting the values, we get

Force = 11143 Pa × 2.02 m²

or

Force = 22508.86 N
