Reduced pressure, abbreviated as \(p_r\), of a fluid is the actual pressure.
Reduced Pressure formula |

| \( p_r = p\;/\;p_c \) | ||
| Symbol | English | Metric |
| \( p_r \) = reduced pressure | \(lbf\;/\;in^2\) | \(Pa\) |
| \( p \) = pressure | \(lbf\;/\;in^2\) | \(Pa\) |
| \( p_c \) = critical pressure | \(lbf\;/\;in^2\) | \(Pa\) |
