Normal Shock Table

    I am wondering, on a Normal Shock Table, what are the two most right columns supposed to mean?

    What is the ratio P02/P01 and P1/P02 supposed to be?

    [itex]p_{02}/p_{01}[/itex] is how the total pressure changes across the shock and is essentially a measure of how dissipative the shock is since total pressure loss is a result of the entropy gained across the shock.

    [itex]p_1/p_{02}[/itex] is effectively just a ratio that is useful in some calculations.
