Reflection Factor Overpressure

Ratio of the peak overpressures reflected to the incident shock wave for a special case of vertical reflection

c_{r} = \frac{8 \cdot {\hat{p}}_{10} + 14 \cdot p_{0}}{{\hat{p}}_{10} + 7 \cdot p_{0}}

c_r	Reflection factor overpressure
p₁₀	Maximum peak overpressure of remote explosion (Kinney & Graham) [kPa]
p₀	Atmospheric pressure under normal conditions (101.3 [kPa])
