Question: In problem 15-3-14 [BNF] determine the diffuser efficiency if the shock is (a) at the inlet and (b) at the exit (%). Problem 15-3-14 Air
Problem 15-3-14
Air approaches a diffuser with a pressure of 20 kPa at a Mach number of 2. A normal shock occurs at the inlet of the channel as shown in the accompanying figure. For an exit to inlet area ratio of 3, find (a) the loss of total pressure and (b) the Mach number at the exit. (c) What-if Scenario: What would the answers be if the shock occurred at the exit?
