Problem 4.
A Mach 3 flow of air flows past a wall as shown. The flow is isentropic and
irrotational. A bump on the wall is thin enough that the flow can be treated with
linearized theory. The bump has a shape given by the function
01
.

x
y
, which is
valid between -0.1 <
x
< 0.1. Both
x
and
y
have units of
meters
.
(a) What is the net force per unit span that acts on the bump in the
x
-direction?
(b) What is the minimum temperature in the flowfield?
(c) Estimate the Mach number at the location in the flow where (x=0.1, y=0.05).
