(a) Explain the difference between static, sonic, total, and freestream quantities. De- scribe their relationships. (b) Is the total/stagnation pressure of a fluid always higher than the static pressure? Are there any cases where the two are equal, or where the stagnation pressure is lower than the static pressure? (c) What must be true when the total density is constant throughout a steady, adi- abatic flow? (a) Explain the difference between static, sonic, total, and freestream quantities.
