Normal Shock Table: P02/P01 & P1/P02 Meaning

Click For Summary

SUMMARY

The Normal Shock Table features two critical columns: the ratios P02/P01 and P1/P02. The ratio P02/P01 indicates the change in total pressure across the shock, serving as a measure of the shock's dissipative nature due to entropy gain. Conversely, the ratio P1/P02 is a useful parameter for various calculations related to shock wave dynamics.

Hello,

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.
