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.
The ARC Moving Ground Wind Tunnel. The ARC wind tunnel is one of the world leading tools used in aerodynamic development today. Our tunnel can test up to 50% scale models replicating full scale racing, production, commercial, and military vehicles to a very high level of detail.
