Question

atmospheric pressure is nearly 100 kPa . How large the force does the air in a a room exert on the inside of a window pan that is 40cm×80cm?

Answer 1

area of window = 0.4m × 0.8m = 0.32 m^2

pressure= 100 kpa

Force = Pressure×area = 100 kpa × 0.32 = 32kN

32 kN force is exerted by air on the window

Answer 2

32 kN.... hope it helps
