Answer:

14.7 psi is equal to 19051.2 pounds per square yard.

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:

[tex]p = 14.7\,\frac{lbf}{in^{2}}\times 1296\,\frac{in^{2}}{yd^{2}}[/tex]

[tex]p = 19051.2\,\frac{lbf}{yd^{2}}[/tex]

14.7 psi is equal to 19051.2 pounds per square yard.
