Question 198290
{{{e=140*sqrt(p)}}} Start with the given equation.



{{{275=140*sqrt(p)}}} Plug in e=275



{{{275/140=sqrt(p)}}} Divide both sides by 140.



{{{1.96429=sqrt(p)}}} Divide



{{{(1.96429)^2=p}}} Square both sides



{{{p=3.85844}}} Rearrange the terms and square 1.96429 to get 3.85844



So the pressure is approximately 3.85844 psi
