Some concepts explored were Bernoulli’s Principle, which states that as the wind speed increases, the pressure decreases, as well as the wind power relationship and the relationship between various factors such as turbine height, wind velocity, and air density and pressure. In this lab, many different designs for turbine blades were tested. Along with this, differing numbers of blades ranging from 2 to 6, as well as two different angles the blades placed on the hub of the turbine, those being 30 and 45 degrees, were tested to determine the greatest power output. A power supply company needed to know the best location for a turbine to power a housing complex. The results of this lab would allow the group to make an educated recommendation for an effective location of the turbine.

Some significant trends were noticed as the group progressed through the lab procedure. As discovered, the most effective angle of the hub was 30 degrees rather than 45 degrees. According to the data, as the number of blades was increased, the power output also increased. Additionally, the higher the voltage applied to the turbine, the greater the power output, which also correlated with a higher wind speed. Thus, the 6 bladed design with the greatest wind speed (determined by the voltage) produced the highest power output, with the angle being at 30 degrees. In the experiment, the greatest source of error was likely the exactitude of the scalar quantities of power output. This error was due to the difficulty of increasing the power supply at a steady rate, and then keeping the values exact without slight fluctuations of voltage supplied. A solution to this error would be to use a computer, instead of the manual turning of a nozzle from a human, to increase this supply uniformly and ensure that all the voltage increments were correct. In conclusion, it was found that a turbine would be able to power the housing complex as it produced 24,725.03 kWh/day, far above the necessary energy of the housing complex, which was 2,000 kWh/day. Based on these results, it was determined that a turbine placed east of Lima, Ohio, in an area with an average wind speed of 7 meters per second, would be most effective in powering the 40-house housing complex. It was also concluded that a greater number of blades, a 30-degree angle, and thin and pointed blades all correlated to higher wind speeds and greater power output at a voltage of 12 volts. The group recommends thin and pointed blades of turbine, with 6 blades attached at a 30-degree angle, as these factors allow for the greatest power production and thus would have the greatest effect on energy supply for this housing complex.
