Calculate the entropy changes of air and helium across the normal shock wave in Prob. 17-96. Air

Question:

Calculate the entropy changes of air and helium across the normal shock wave in Prob. 17-96.
Air flowing steadily in a nozzle experiences a normal shock at a Mach number of Ma = 2.6. If the pressure and temperature of air are 58 kPa and 270 K, respectively, upstream of the shock, calculate the pressure, temperature, velocity, Mach number, and stagnation pressure downstream of the shock.
Compare these results to those for helium undergoing a normal shock under the same conditions.
