Pressure Ratio Solution

STEP 0: Pre-Calculation Summary

Formula Used

Pressure Ratio = Final Pressure/Initial Pressure
P_R = P_f/P_i
This formula uses 3 Variables

Variables Used

Pressure Ratio - Pressure Ratio is ratio of final to initial pressure.
Final Pressure - (Measured in Pascal) - Final Pressure is the pressure of a fluid or gas at the conclusion of a process or within a system.
Initial Pressure - (Measured in Pascal) - Initial Pressure refers to the pressure of a fluid or gas at the beginning of a process or within a system.

STEP 1: Convert Input(s) to Base Unit

Final Pressure: 259 Pascal --> 259 Pascal No Conversion Required
Initial Pressure: 65 Pascal --> 65 Pascal No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P_R = P_f/P_i --> 259/65

Evaluating ... ...

P_R = 3.98461538461538

STEP 3: Convert Result to Output's Unit

3.98461538461538 --> No Conversion Required

FINAL ANSWER

3.98461538461538 ≈ 3.984615 <-- Pressure Ratio
