Answer:
The Power output from Turbine B with the doubled blade will be X4 of the power output from Turbine A.
Explanation:
The Power generated by a wind turbine is governed by the equation:
P=0.5ρAV³
Where ρ= Air Density
A= Swept Area of the Blade =πr²
V= Wind Velocity
If they are subjected to the same wind, Air Density and Wind Velocity will be equal
For both turbines,
Let Air Density=1
Wind Velocity=1
Power from Turbine A = 0.5X1XπX1²=0.5π
Power from Turbine B (radius=2) = 0.5X1XπX2²=2π
Power from Turbine B/Power from Turbine A = 2π/0.5π=4
Answer:
As a skydiver falls, he accelerates downwards, gaining speed with each second. The increase in speed is accompanied by an increase in air resistance so it depends
