1. The problem statement, all variables and given/known data Air within the funnel of a large tornado may have a pressure of only 0.2 atm. Atmospheric pressure is 101300 Pa. What is the approximate outward force F on a 11m X 16 m wall if a tornado suddenly envelopes the house? Answer in units of N. 2. Relevant equations P = F/A 3. The attempt at a solution I converted 0.2 atm to 20260 Pa. The area is 11m X 16 m = 176 m^2. F = (20260 Pa) (176 m^2) F = 3.56576 X 10^6 N The answer is wrong. What did I overlook?
