Absolute Pressure Calculator
Top
Absolute pressure calculator is an online tool to calculate the absolute pressure. Absolute pressure is nothing but the pressure above the absolute zero. In other words, it is defined as the sum of gauge pressure and atmospheric pressure.


$P_{a}$=$P_{g}$+$P_{at}$

Where $P_{a}$ is the absolute pressure
           $P_{g}$ is the gauge pressure
           $P_{at}$ is the atmospheric pressure

  1. Determine the absolute pressure if the gauge pressure is 98541 Pa and atmospheric pressure is 101325 Pa?


    Step 1 :  

    The given values are,


    $P_{g}$=98541 Pa and $P_{at}$=101325 Pa



    Step 2 :  

    We have to find out the absolute pressure. So the equation is,


    $P_{a}$=$P_{g}$+$P_{at}$=199866 Pa



    Answer  :  

    Absolute pressure is,

    $P_{a}$=199866 Pa



  2. If the absolute pressure is given as 187523 Pa, calculate the guage pressure provided $P_{at}$=101325 Pa?


    Step 1 :  

    It is given that,


    $P_{at}$=101325 Pa, $P_{a}$=187523 Pa, $P_{g}$=?



    Step 2 :  

    The absolute pressure formula is


    $P_{a}$=$P_{g}$+$P_{at}$


    We have to find out $P_{g}$. So the formula become,


    $P_{g}$=$P_{a}$-$P_{at}$


    $P_{g}$=187523-101325=86198 Pa



    Answer  :  

    Gauge pressure is equal to

    $P_{g}$=187523-101325=86198 Pa
