The total pressure across a shock wave in a supersonic flow, denoted as , is the sum of the static pressure and the dynamic pressure after the flow has passed through the shock. It represents the total energy of the flow, which includes both pressure energy and kinetic energy due to the flow velocity.
- Total pressure across the shock (p0,2) in N/m^2
- Ratio of total pressure across the shock to the behind the shock (p0,2/p0,1)
- Ratio of total pressure behind the shock to the static pressure (p0,1/p1)
- Static pressure (p1) in N/m^2
