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.

A converging–diverging nozzle with a 4:1 exit-area ratioand p0 = 500 kPa operates in an underexpanded condition as in Fig. The receiver pressureis pa = 10 kPa, which is less than the exit pressure sothat expansion waves form outside the exit.

An ideal gas is to flow isentropically from a large tank where the air is maintained at a temperature and pressure of 59 °F and 76 psia to standard atmospheric discharge conditions in a way to achieve a maximal velocity. Describe in general terms the kind of duct involved and determine the duct exit Mach number and velocity in ft/s if the gas is air. The problem can be solved either using the isentropic relations or this figure. The isentropic relations are more accurate, but difficult to use unless you code them into a computer program.
