Question

An office window has dimensions 3.7 m by 2.1 m. As a result of the passage of a storm, the outside air pressure drops to 0.972 atm, but inside the pressure is held at 1.0 atm. What net force pushes out on the window?

    Answer:

    22044.3 N

    Explanation:

    We are given that

    Dimension of office window=3.7m\times 2.1 m

    Area of office window=l\times b=3.7\times 2.1=7.77 m^2

    Outside air pressure=P1=0.972 atm

    Inside pressure,P2=1.0 atm

    Pressure=P2-P1=1-0.972=0.028 atm=0.028\times 101325 Pa=2837.1 Pa

    1 atm=101325 Pa

    Force,F=PA

    Using the formula

    F=7.77\times 2837.1=22044.3 N

    Hence, the net force pushes out on the window=22044.3 N
