Question

A gauge reads 45 psi. The absolute pressure is _?

Answer 1

I think 1 atm = 14.5 PSI at STP, so the absolute can be figured as (gauge + standard atmosphere)

Answer 2

So 45 + (45*14.5)?

Answer 3

just the sum. 45+14.5 = absolute pressure (in psi)

Answer 4

thanks!

Answer 5

If the gauge reads zero, it's still actually under 1atm of pressure, right?

Answer 6

I believe so
