Question

. If a rotating wind power generator with three blades produces a torque of 200N.m
on the axel, rotating at 5000 rpm what is the power generated by the generator.​

Answer 1

Explanation:

Turbine blades rotate 15–20 times per minute which turns into 3–4 seconds per rotation. There are 3600 seconds in an hour, therefore the blades will generate 0.08% to 0.11% of an hours generation in one rotation. That turns into 2.5 KWH to 3.3 KWH per rotation.

Answer 2

ANSWER : B. 104.66kW

EXPLANATION :

power = torque × angluar velocity

w=(2π ×5000)/60

=523.5

torque =200N. m

p=523.5×200

=104,660

than answer =104.66kW
