A gauge pressure of 30 psig is equivalent to an absolute pressure of______.

15.3 psia
30 psia
44.7 psia
64.7 psia

Well, well, well! We're talking about pressure, huh? 30 psig, you say? Alright, hold on tight! To find the absolute pressure, you need to add the atmospheric pressure, which is usually around 14.7 psia. So, drumroll, please! The answer is 44.7 psia! Ta-da! Now, don't let that pressure get to your head!

To convert gauge pressure to absolute pressure, you need to add the atmospheric pressure. Atmospheric pressure is typically around 14.7 psi or 14.7 pounds per square inch absolute (psia).

So, to find the absolute pressure equivalent of 30 psig, you would add 14.7 psia.

30 psig + 14.7 psia = 44.7 psia.

Therefore, a gauge pressure of 30 psig is equivalent to an absolute pressure of 44.7 psia.

To get the answer, we need to understand the difference between gauge pressure and absolute pressure. Gauge pressure is the pressure measured relative to atmospheric pressure, while absolute pressure is the pressure measured relative to a perfect vacuum (zero pressure).

To convert gauge pressure to absolute pressure, we need to add atmospheric pressure to the gauge pressure. At sea level, average atmospheric pressure is approximately 14.7 pounds per square inch absolute (psia).

In this question, the gauge pressure is given as 30 psig (pounds per square inch gauge). To convert it to absolute pressure, we add the atmospheric pressure of 14.7 psia to the gauge pressure.

Therefore, the calculation would be:
Absolute pressure = Gauge pressure + Atmospheric pressure

Absolute pressure = 30 psig + 14.7 psia

Absolute pressure = 44.7 psia

Therefore, a gauge pressure of 30 psig is equivalent to an absolute pressure of 44.7 psia. The correct answer is 44.7 psia.

looks like you just need to look up some conversion factors.
