Assuming mass does not also increase, then density decreases if volume increases. For example, let's say Mass= 100 and Volume= 50 Density would = 2 Now, lets increase the voluâ¦me. Mass would still = 100, and let's increase the volume to 75. Density would then equal 1.333... 2 is greater than 1.333....
Definition of wind tunnel. : a tunnellike passage through which air is blown at a known velocity to investigate air flow around an object (such as an airplane part or model) placed in the passage.
Anechoic Wind Tunnel. The FSU Anechoic Wind Tunnel is an open-circuit subsonic facility which has a 36â x 48â x 120â test section with a speed range of approximately 18-75 m/s. The facility employs a 450-hp centrifugal fan and has an anechoic chamber with a 250 Hz cut-on frequency enclosing the test section.
