1. The problem statement, all variables and given/known data Suppose that a blast wave, which might have been initiated by an atomic bomb explosion, is traveling through air at standard atmospheric conditions with a speed of 60,000 m/s find change in ( pressure , temperature , stagnation pressure , velocity ) produced by the wave with respect to an observer who is stationary with respect to the undisturbed air. 2. Relevant equations v= M*sqrt(gamma*R*T) isentropic tables & Normal Shock Wave Tables. 3. The attempt at a solution i'm trying to use the equation v=M sqrt(gamma*R*T) with air p=103.5 kpa , T=298K , but i can't seem to understand the problem , since i get M=180 which is obviously wrong.
