Scenario $4$:

You decided to implement a new renewable power generation system to reduce electricity bills of your

farmhouse. You must decide whether to go for solar or wind power. Answering the following questions will

help you make up your mind.

Task $7$:

If you have a wind turbine with the specification shown in table $3$ below, and given the wind speed profile

shown in table $4$ and figure $12$ :

Table $3$

Table $4$

Complete the table with the average produced power in the corresponding time interval.

Calculate average wind speed, average power production, and predict the total produced energy in

that day.

What do you expect in the following scenarios:

a$)$ The number of blades were increased to $5.$

b$)$ The swept area of the turbine was increased.

c$)$ The cut$-$in wind speed was reduced to $4\frac{m}{s}.$

d$)$ The blades angle of attack was changed.

e$)$ If the propeller shaft of the turbine was attached to a gear with $N$ number of teeth,

what do you expect if this number was increased?
