Entropy

In physics, entropy means the amount of disorder or the degree of randomness associated with a thermodynamic system. The system is not self-organized when the entropy of the system is high. For instance, when a system is at an elevated temperature, its molecules are in random motion, vibrating and colliding with each other. During this scenario, the probability of finding a molecule at a particular place twice, is low. Under this circumstance, the system can be said to be in a high entropy.

Question

A blunt-nosed aerodynamic model is mounted in the test section of a
supersonic wind tunnel. If the tunnel reservoir pressure and temperature are
10 atm and 800°R, respectively, and the exit-to-throat area ratio is 25,
calculate the pressure and temperature at the nose of the model.
