In vertical axis highway wind mill normally have four c-type blades that are placed in vertical direction. These four blades have normally separated by 90-degree angle with each other. So that in highways when vehicle passes the VAHW will rotate in clockwise direction.. The wind turbine blade design has been decided and
6. A sump design velocity of 1 foot per second at minimum water level is good practice. If some elements of good practice must be violated in a given sump design, the detrimental effects may be reduced by lowering the velocity of flow in the sump.

The vertical axis wind turbine is a small power generating unit with the help of free source of wind energy.It is designed under consideration of household use.The analysis results of the wind turbine governs that the design is under safe limit.It is check in analysis for worst condition working by using velocity
Oct 31, 2014 When I was a Senior Mechanical Engineering student at the University of Pittsburgh, in 1975, our senior design project was to develop a vertical shaft windmill. It was very difficult to generate enough power, even with higher wind velocities we simulated with high pressure air in a venturi.
