A Gauge pressure of 30 psig is equivalent to an absolute pressure of
15.3 psia
30 psia
44.7 psia
64.7 psia
absolute = gauge + ambient
ambient is usually atmospheric ... 14.7 psi
got it, thank you.
To convert gauge pressure to absolute pressure, you need to add the atmospheric pressure (also known as the reference pressure) to the gauge pressure.
The atmospheric pressure at sea level is approximately 14.7 pounds per square inch absolute (psia).
To find the absolute pressure, add the atmospheric pressure to the given gauge pressure:
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 determine the absolute pressure equivalent to a gauge pressure, you need to add the atmospheric pressure to the gauge pressure. Atmospheric pressure is typically around 14.7 pounds per square inch absolute (psia) at sea level.
In this case, the gauge pressure is given as 30 psig, which stands for "pounds per square inch gauge." To convert it to absolute pressure, you need to add 14.7 psia.
Therefore, the absolute pressure equivalent to a gauge pressure of 30 psig is calculated as:
30 psig + 14.7 psia = 44.7 psia
So, the correct answer is 44.7 psia.
