Problem 18P

At a certain location, wind is blowing steadily at 8 m/s. Determine the mechanical energy of air per unit mass and the power generation potential of a wind turbine with 50-m-diameter blades at that location. Also determine the actual electric power generation assuming an overall efficiency of 30 percent. Take the air density to be 1.25 kg/m3.

Step-by-Step Solution:

Solution to 18P

Step 1</p>

We need to find the mechanical energy per unit mass and the power generation potential of wind turbine with radius 25m. The generator have a power generation efficiency of 30%.

Step 2</p>

We know that the mass and volume flow rate is related by the following equation,

 is the volume flow rate.

v=velocity of fluid flow

A= Cross Sectional area

Therefore,
