Problem 3 (30 points): Flow enters a duct with its top and bottom walls are oriented at different angles with respect to the upstream approach flow. The waves shown are expansion waves. a) Calculate the Mach number and the flow direction in section 4. 5 M=1.5 15 section 4 Problem 3 (30 points): Flow enters a duct with its top and bottom walls are oriented at different angles with respect to the upstream approach flow.
