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

What is pressure ratio?

Pressure ratio is the ratio of final pressure after process to the initial pressure before process. It gives the degree with which gas is compressed.

How to Calculate Pressure Ratio?

Pressure Ratio calculator uses Pressure Ratio = Final Pressure/Initial Pressure to calculate the Pressure Ratio, The Pressure ratio formula is defined as the ratio of the final pressure after process to the initial pressure before process. Pressure Ratio is denoted by P_R symbol.

How to calculate Pressure Ratio using this online calculator? To use this online calculator for Pressure Ratio, enter Final Pressure (P_f) & Initial Pressure (P_i) and hit the calculate button. Here is how the Pressure Ratio calculation can be explained with given input values -> 3.984615 = 259/65.

FAQ

What is Pressure Ratio?

The Pressure ratio formula is defined as the ratio of the final pressure after process to the initial pressure before process and is represented as P_R = P_f/P_i or Pressure Ratio = Final Pressure/Initial Pressure. Final Pressure is the pressure of a fluid or gas at the conclusion of a process or within a system & Initial Pressure refers to the pressure of a fluid or gas at the beginning of a process or within a system.

How to calculate Pressure Ratio?

The Pressure ratio formula is defined as the ratio of the final pressure after process to the initial pressure before process is calculated using Pressure Ratio = Final Pressure/Initial Pressure. To calculate Pressure Ratio, you need Final Pressure (P_f) & Initial Pressure (P_i). With our tool, you need to enter the respective value for Final Pressure & Initial Pressure and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
