What is the absolute pressure if there is a gauge pressure of #3.2*m# of water?

Question

Olivia Askew · Accepted Answer

Does not a #10.06*m# column of water exert a pressure of #1*"bar"#?

And thus a column of water #3.2*m# water has a gauge pressure of #(3.2*m)/(10.06*m*"bar"^-1)-=0.318*"bar"#....and an absolute pressure of #1.318*"bar"#....

Adrian Ayala · Answer

undefined The absolute pressure is the sum of the gauge pressure and the atmospheric pressure. Assuming the atmospheric pressure is 1 atm, the absolute pressure can be calculated as follows:

Absolute pressure = Gauge pressure + Atmospheric pressure
Absolute pressure = 3.2 m of water + 1 atm

To convert meters of water to atmospheric pressure, we use the conversion factor that 1 m of water is approximately equal to 0.098 atm.

So, 3.2 m of water is approximately 0.098 * 3.2 atm = 0.3136 atm.

Adding this to the atmospheric pressure:

Absolute pressure = 3.2 m of water + 1 atm
Absolute pressure ≈ 0.3136 atm + 1 atm
Absolute pressure ≈ 1.3136 atm

Therefore, the absolute pressure is approximately 1.3136 atm.

undefined The absolute pressure is the sum of the gauge pressure and the atmospheric pressure. Assuming the atmospheric pressure is approximately 101.3 kPa (standard atmospheric pressure at sea level), you would add the gauge pressure of 3.2 meters of water to the atmospheric pressure to find the absolute pressure.
