Question #1387

Air within the funnel of a large tornado may
have a pressure of only 0.19 atm.
What is the approximate outward force F
on a 9.1 m × 26 m wall if a tornado suddenly
envelopes the house? Atmospheric pressure is 1.013 × 105 Pa.
Answer in units of N.

Expert's answer

As in 1 atm is 1.013 × 10^{5} Pa, in 0.19 atm would be 0.192 × 10^{5} Pa.

Let's find the area of the wall: S = 9.1* 26 = 236.6 m^{2}.

Thus:

F = PS = 0.192 × 10^{5 }* 236.6 = 4.543 × 10^{6 }N.

Let's find the area of the wall: S = 9.1* 26 = 236.6 m

Thus:

F = PS = 0.192 × 10
