Your Challenge

Now that you’ve constructed and coded your Wind Turbine here are some challenges for your to complete.

Let’s say that the average house requires 500 watts of power for 1 day of electricity.

Calculate how many minutes your wind turbine would need to spin at 10 RPMs to generate 500 watts of power, if 10 RPMs = 2 watts of power.

Remember, 10 RPMs = 10 revolutions in 1 minute and 1 minute running at 10 RPMs = 2 watts of power
Your answer will be calculated in minutes – how could you calculate this answer in hours?

If the wind turbine generates 2500 watts of power at a speed of 25 RPMs running for 500 minutes, how much power is generated per revolution?

First, start by calculating the total number of revolutions: Speed (RPMs) x Time (minutes)
Then, you can calculate the power per revolution by dividing the total watts by the total number of revolutions you calculated above.
