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.
Part of the Electronics glossary: A wind turbine is a power generating device that is driven by the kinetic energy of the wind. Wind turbines general fall into one of two categories: Horizontal axis wind turbines (HAWTs) and vertical axis wind turbines (VAWTs). HAWTs, the more common type, consist of propeller-like rotors fixed around a central hub and facing into the wind, like a windmill.
