Solving for working pressure.

#### Inputs:

 internal pressure (P) pascalatmospherebardyne/centimeter^2foot of waterinch of mercuryinch of waterkilonewton/meter^2millibarmillimeter of mercurynewton/meter^2pound/foot^2pound/inch^2torr
 maximum surge pressure (Psurge) pascalatmospherebardyne/centimeter^2foot of waterinch of mercuryinch of waterkilonewton/meter^2millibarmillimeter of mercurynewton/meter^2pound/foot^2pound/inch^2torr

#### Conversions:

 internal pressure (P)= 0 = 0pound/inch^2
 maximum surge pressure (Psurge)= 0 = 0pound/inch^2

#### Solution:

 working pressure (Pwork)= NOT CALCULATED
