Normal Shock Flow Functions

For a flow through a normal shock, with no direction change, area change, or work done, the governing equations are:

Continuity
Momentum
Energy
From these identities, relationships can be derived which explain the condition of the flow for both state 1, before the shock, and state 2, after the shock as follows:
		Mach#, M = sqrt (gRT)
From these relationships, the following table has been published for easy reference:
