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.
Low Speed Wind Tunnel The Low speed wind tunnel facility has a 30â x 30â x 60â test section and a speed range of 2 to 70 m/s. The facility will be used to carry out measurements on a wide range of test articles to develop innovative, practical active flow control techniques and advanced diagnostics to study the design of, and fundamental problems in low-speed flight vehicles.
