Work Time Team member Bart Ring diligently working with the finer aspects of the project. Lane Dukart studies his math calculations Garrett Rich spices up the power point presentation
3
Materials DC motor – generator Cardboard - propellers Molding Clay/Krazy Glue - Support of the base PVC Pipe - Framework of windmill Duct Tape - Everything Butt Splice - Wire Wood Block – Base Drill Head – Cranks generator
4
Equations for Windmill Power = Amps x Voltage Amps =.0125 Voltage =.8 volts Power = (.0125) x (.8) =.01 volts
5
Equations for Air Power =.5 x p x Area x Velocity 2 p = 1.204 Radius of Fan =.2 meters Area of Fan = pi x.04 m =.125 meters 2 Windspeed = 22 mph = 9.83 m/s Power =.5 x 1.204 x.125 x 9.83 3 = 71.5
6
Efficiency Equation Efficiency = (power mill / power air ) x 100 Efficiency = (.01 / 71.5) x 100 =.0139 % Killer efficiency
7
Conclusion We took a different path in building our windmill than the other groups. We used what was around us and put together a horribly efficient, but workable windmill. We had a blast making this windmill, half the fun was wondering if the device would produce us some power.
