1. Design a system that has no moving mechanical parts to cool machine shop compressed air at 0.500 MPa, 25.0°C to 0.00°C at 0.101 MPa. The outlet velocity must be at least 10.0 m/s. If possible, fabricate and test your design.
2. Design a small demonstration wind tunnel to be driven from a standard compressed air supply line at 100. psia and 70.0°F. Assume that the maximum volumetric air flow rate available from this supply is 10.0 ft3 /min at 14.7 psia and 70.0o F. The wind tunnel test section must be at least 1.00 inch in diameter and must reach a Mach number of at least 2.25.
The air may be exhausted to the atmosphere, but it first must be decelerated to subsonic velocity to minimize noise generation. If possible, fabricate and test your design.
