# Wind Turbine Energy Calculator, Formula, Wind Turbine Energy Calculation

## Wind Turbine Energy Calculator:

Enter the values of Radius of the Turbine r(m), Velocity of Wind v(m/s) , Density of the Air p(1.225 kg/m3), Efficiency Factor n(%) & Time of Wind Power Generation t(sec) to determine the value of Wind Turbine Energy E(J).

 Enter Radius of the Turbine: m Enter Velocity of Wind: m/s Enter Efficiency Factor: % Enter Time of Wind Power Generation: sec Result – Wind Turbine Energy: J

## Wind Turbine Energy Formula:

The Wind Turbine Energy E(J) in Joules is Equal to the 3.141 is Divided by the 2 into Multiply to the Radius of the Turbine r(m) in meter and is squared and Multiply the Velocity of Wind v(m/s) in meter per second and is squared and Multiply the Density of the Air p(1.225 kg/m3) in 1.225 kilogram per meter cube and Multiply to the Efficiency Factor n(%) in percentage and again Multiply the Time of Wind Power Generation t(sec) in second.

The Equation of Wind Turbine Energy can be written as,

E(J) = 3.141 / 2 * r2(m) * v2(m/s) * p(1.225 kg/m3) * n(%) * t(sec)

Here,

E(J) = Wind Turbine Energy in Joules

r(m) = Radius of the Turbine in meter

v(m/s) = Velocity of Wind in meter per second

p(1.225 kg/m3) = Density of the Air in 1.225 kilogram per meter cube

n(%) = Efficiency Factor in percentage

t(sec) = Time of Wind Power Generation in second

### Wind Turbine Energy Calculation:

1) Calculate the Wind Turbine Energy and given for the Radius of the Turbine = 6m, Velocity of Wind = 50m/s, Density of the Air = 1.225kg/m3, Efficiency Factor = 35%, Time = 7sec.

E = 3.141 / 2 * r2 * v2 * p * n * t

E = 3.141 / 2 * 62 * 502 * 1.225 * 35/100 * 7

E = 0.00000581424 Joules.

2) Calculate the Time and given for the Radius of the Turbine = 6m, Velocity of Wind = 50m/s, Density of the Air = 1.225kg/m3, Efficiency Factor = 35%, Wind Turbine Energy = 0.00000581424 Joules.
