What is absolute pressure?

Absolute pressure is simply the addition of the observed gage pressure plus the value of the local atmospheric pressure.


What is the formula for absolute pressure?

but i think the absolute pressure is P(pressure)/{p(density)*g(gravity)}


What is the absolute pressure of -0.2 bar?

Absolute pressure is calculated by adding atmospheric pressure to the gauge pressure. Standard atmospheric pressure is approximately 1.01325 bar, so for a gauge pressure of -0.2 bar, the absolute pressure would be 1.01325 bar - 0.2 bar, which equals approximately 0.81325 bar. Therefore, the absolute pressure is about 0.813 bar.


Gauge pressure and absolute pressure?

Gauge pressure is what you get when you take the reading from your tire pressure gauge. Absolute pressure is the pressure inside your tires plus the atmospheric pressure, which is roughly; 14.7 psi, 101.3 kPa (kilo-Pascals), or one atmosphere. Absolute pressure measures all of the pressure on your tires, inside and out, whereas gauge simply measures the pressure inside the tire.


What is the absolute pressure in a piping system when the vacuum gauge reads 20 inches and the barometer reads 30.71 inches of mercury?

To find the absolute pressure in the piping system, you can convert the vacuum gauge reading to absolute pressure using the barometric pressure. The absolute pressure (P_abs) can be calculated as follows: P_abs = P_atm - P_vacuum = 30.71 inches of mercury - 20 inches of mercury = 10.71 inches of mercury. Thus, the absolute pressure in the piping system is 10.71 inches of mercury.
