I'm taking an advanced course and learning about gauge pressure vs. absolute pressure. A take home test question is as follows:
"The gauge pressure at a depth of 59 feet in fresh water is ____ psig and the absolute pressure is ___ psia."
Is this another way of asking about ATM vs ATA? I know that 59 ffw is 1.7 ATM (depth of 59' divided by 34'). I know that ATA would then be 2.7.
But seeing "psig" and "psia" I assume its asking for a different computation that I don't understand. I've tried to find online and I'm lost.
Any wisdom on this?
