Respuesta :

[tex]\begin{gathered} P=\frac{F}{A} \\ \text{Where:} \\ P=14.7\text{ } \\ A=7.5 \end{gathered}[/tex]

Solving for F:

[tex]\begin{gathered} F=P\times A \\ F=14.7\times7.5=110.25 \end{gathered}[/tex]

F = 110.25in²

The answer is reasonable because the pressure is inversely proportional to the area over which it is exerted, the head area is considerable, so the pressure is low
