Question

Consider the window (of area 0.68 m2) of an airplane. If the pressure inside the plane is atmospheric pressure, while the pressure outside is 31 % of Patm, find the force on the window. Ignore the velocity of the airplane (i.e., ignore Bernoulli’s effect).

Answer 1

(1 -0.31)*Patm*(window area)= ___ N/m^2

Patm refers to the normal seal level pressure, 1.013*10^5 N/m^2
