After being purged with nitrogen, a low$-$pressure tank used to store flammable liquids has a gauge pressure of $0\mathrm{.}03$ psig.

If the tank was purged in the morning when its contents were at $55F,$ what is the pressure in the tank later in the afternoon when the ambient temperature is $85F?$

If the maximum design gauge pressure of the tank is $8$ inches of water, has the design pressure been exceeded? $($note$,$ there is an error in the conversion factor table in the front cover of the textbook to convert psi to $i{n}_{H2O}.$ Use $1=27\mathrm{.}7076i{n}_{H2O}).$
