Ratio of static pressure on top of the plate to the static pressure on bottom of the plate across the expansion wave Calculator

In aerodynamics, an “expansion wave over the top of the flat plate” refers to a specific flow phenomenon that occurs when a supersonic flow interacts with the upper surface of a flat plate. The “expansion wave over the bottom of the flat plate” refers to a specific flow phenomenon that occurs when a supersonic flow interacts with the lower surface of a flat plate. 

• Ratio of total pressure at bottom of the plate to the static pressure of bottom of flat plate (p01/p1)
• Ratio of total pressure at top of the plate to the static pressure of top of flat plate (p02/p2)
• Ratio of static pressure on top of the plate to the static pressure on bottom of the plate (p2/p1)
