What is the Stagnation Pressure of a Body Moving Through Air?

[rohit_patel]

A body moves through air at a velocity of 200 m/s. The pressure and temperature in
the air upstream of the body are 100 kPa and 30◦ C respectively. Find the pressure
at a point on the body where the velocity of the air relative to the body is zero (1)
accouting for compressibility and (2) assuming incompressible flow. Assume that the
flow is isentropic.


I have no clue! Please, help me! I'm in way over my head here.
