Wind Turbine Energy Formula
The following equation is used to calculate the Wind Turbine Energy.
E = pi/2*r^2*v^2*p*n*t
- Where E is the Wind Turbine Energy (Joules)
- r is the radius of the turbine (m)
- v is the velocity of wind (m/s)
- n is the efficiency factor (%)
- T time of wind power generation (s)
- p is the density of the air (1.225 kg/m^3)
How to Calculate Wind Turbine Energy?
The following example problems outline the steps and information needed to calculate the Wind Turbine Energy.
Example Problem #1
- First, determine the radius of the turbine (m). In this example, the radius of the turbine (m) is determined to be 5 .
- Next, determine the velocity of wind (m/s). For this problem, the velocity of wind (m/s) is measured to be 49 .
- Next, determine the efficiency factor (%). In this case, the efficiency factor (%) is found to be 34.
- Next, determine the time of wind power generation (s). For this problem this is 5 seconds.
- Finally, calculate the Wind Turbine Energy using the formula above:
E = pi/2*r^2*v^2*p*n*t
Inserting the values from above and solving the equation yields:
E = 3.14159/2*5^2*49^2*1.225*34/100*5 = 196352 Joules
Example Problem #2
Using the same method as above, first, we need to measure or determine the variables required by the equation. For this example problem, these are provided as follows:
radius of the turbine (m) = 93
velocity of wind (m/s) = 5
efficiency factor (%) = 3
time (s) = 3
Enter these given values into the calculator or above yields: E = 3.14159/2*93^2*5^2*1.225*3/100*3 = 37445.877 (Joules)
