Atmospheric pressure is nearly 100 kPa. ...

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

Text Solution

Verified by Experts

Atmospheric pressure = 100 kPa
`= 10^(5) Pa`
Area, A = 40 cm `xx` 80 cm
= 40 `xx 80 xx 10^(-4) m^(2)`
F = P `xx` A
`= 10^(5) xx 3200 xx 10^(-4)`
= 32 kN.
