Question

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

Answer 1

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

Step-by-step explanation:

To force is given by:

`F = P*A` (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:

`F = P*A = 14.7 (lb)/(in^(2))*(4.45 N)/(1 lb)*(1550 in^(2))/(1 m^(2))*1 m^(2) = 101.4 kN`

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

I hope it helps you!
