Final answer:
The pressure of the PSIA at sea level under standard conditions is approximately 14.7 psi.
Step-by-step explanation:
The pressure of the PSIA at sea level under standard conditions is approximately 14.7 psi.
Standard atmospheric pressure at sea level is equivalent to 1 atm or 760 mm Hg. Using the conversion factor of 1 atm = 14.7 psi, we can determine that the PSIA at sea level is 14.7 psi.
