Given:
Gauge Pressure = 230 psi.
Let's find the absolute pressure of the oxygen in the tank.
To find the absolute pressure, apply the formula:
Absolute Pressure = Gauge Pressure + Atmospheric Pressure
P = Pg + Pa
Where:
Pg is the gauge pressure in Pa.
Pa is the atmospheric pressure = 1.01 x 10⁵ Pa
Convert the gauge pressure from psi to pa:
Where:
1 psi = 6894.76 pa
230 psi = 230 x 6894.76 = 1.586 x 10⁶ Pa.
Hence, to find the absolute pressure, we have:
Absolute pressure = (1.586 x 10⁶) + (1.01 x 10⁵)
Absolute pressure = 1.687 x 10⁶ Pa
Therefore, the absolute pressure of the oxygen in the tank is 1.687 x 10⁶ Pa
ANSWER:
1.687 x 10⁶ Pa
