STEP 0: Pre-Calculation Summary

Formula Used

Reduced Pressure = Pressure/Critical Pressure
P_r = p/P_c
This formula uses 3 Variables

Variables Used

Reduced Pressure - Reduced Pressure is the ratio of the actual pressure of the fluid to its critical pressure. It is dimensionless.
Pressure - (Measured in Pascal) - Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed.
Critical Pressure - (Measured in Pascal) - Critical Pressure is the minimum pressure required to liquify a substance at the critical temperature.

STEP 1: Convert Input(s) to Base Unit

Pressure: 38.4 Pascal --> 38.4 Pascal No Conversion Required
Critical Pressure: 33500000 Pascal --> 33500000 Pascal No Conversion Required
