Question

The surface pressure of the atmosphere is about 14.7 psi (pounds per square inch). How many pounds per square yard does that amount to

Answer 1

14.7 psi is equal to 19051.2 pounds per square yard.

Step-by-step explanation:

Dimensionally speaking, a square yard equals 1296 square inches. Therefore, we need to multiply the atmospheric pressure by 1296 to obtain its equivalent in pounds per square yard. That is:

`p = 14.7\,(lbf)/(in^(2))* 1296\,(in^(2))/(yd^(2))`

`p = 19051.2\,(lbf)/(yd^(2))`

14.7 psi is equal to 19051.2 pounds per square yard.
