Question a pressure gauge reads 231 in hg inches of mercury, Ask an Expert

Academics

Question: A pressure gauge reads 23.1 in Hg (inches of mercury) vacuum (i.e. -23.1 in Hg gauge). The barometer reads 76.0 cm Hg.

Part A: What is the pressure (in psia) in the tank to which the pressure gauge is connected?

Part B: What is this pressure in kPa?

I need expert help to solve the above question.
