What is the absolute pressure if the gauge pressure is 3.2 atm?
To find the absolute pressure when given the gauge pressure, you need to add the atmospheric pressure to the gauge pressure. The atmospheric pressure is the pressure exerted by the Earth's atmosphere, and it is typically around 1 atm at sea level.
So, to find the absolute pressure, you'll need to add the gauge pressure to the atmospheric pressure.
Absolute pressure = Gauge pressure + Atmospheric pressure
In this case, the gauge pressure is given as 3.2 atm. Assuming the atmospheric pressure is 1 atm, you would add 3.2 atm (gauge pressure) to 1 atm (atmospheric pressure).
Absolute pressure = 3.2 atm + 1 atm = 4.2 atm
Therefore, the absolute pressure is 4.2 atm.
