e=140%2Asqrt%28p%29 Start with the given equation.


275=140%2Asqrt%28p%29 Plug in e=275


275%2F140=sqrt%28p%29 Divide both sides by 140.


1.96429=sqrt%28p%29 Divide


%281.96429%29%5E2=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
