Our atmosphere exerts a pressure of 14.7 lb/in2. What is the force on one square foot of the earth’s surface caused by the atmosphere

The force on one square foot of the earth’s surface caused by the atmosphere is 101.4 kN.

Explanation:

To force is given by:

  (1)

Where:

P: is the pressure = 14.7 lb/in²

A: is the area = 1 m²

By entering the above values into equation (1) we have:

Therefore, the force on one square foot of the earth’s surface caused by the atmosphere is 101.4 kN.
