You have been chosen as the chief designer of a subsonic wind tunnel. The test section should have a 1.0m (Height)1.0m (Depth) cross-section and be a minimum 2m long with a design Mach number of 0.6. The tunnel is to be driven by a fan manufactured by ABET ISENTROPIC, Inc. This fan is guaranteed by ABET to do work on the working fluid isentropically. The diagram below shows a "blow down" wind tunnel. The fan is located upstream of the test section in a constant area section A A2. The cross-sectional area of the test section is = A3. Air is exhausted back into the room at exit station 4. Design this wind tunnel. Assume standard air condition outside the tunnel. A1 Fan A2 A4 A3 Electric Energy Test Section 1. Determine what you would choose for A and A; 2. the lengths of the converging and diverging segments before and after the test section; 3. the total pressure ratio of the fan (P02/P01) and power rating for your fan, and therefore the rating of the motor you need to drive the fan.
