. A pressure gage connected to a tank reads 50 psi at a location where the barometric reading is 29.1 Hg. Determine the absolute pressure in the tank.

First, we have to convert the atmospheric pressure into psi. Where an inch of mercury is equal to about 0.491 pounds per square inch

[tex]\sf{(29.1 \: hg)( \dfrac{0.491 \: psi}{1 \: hg} )}[/tex]

[tex]\sf\blue{ = 14.2889 \: psi}[/tex]

The sum of the gauge and the atmospheric pressure is the absolute pressure.

[tex]\sf{P_{abs}= P_{gage} + P_{atm}}[/tex]

[tex]\sf{P_{abs}= 50 \: psi + 14.2889 \: psi}[/tex]

[tex]\boxed{\green{\sf{P_{abs}≈64.29 \: psi }}} [/tex]
