Question

Q1: If the recorded monthly wind speeds recorded in Bahrain as follows: 4.90, 3.8, 6.9, 7.0, 2.9, 4.5, 5.0, 5.3, 5.8, 6.5, 6.8, 4.9, ms1, then estimate the following: 1. The potential of the wind power The maximum extractable electrical power if the efficiency of the wind generator is 35% and the blade size of the wind generator is 5 m and the air density is 1.25 kg m-3 2.

Answer 1

ANSWER-

1. POTENTIAL OF THE WIND POWER =$1/2\rho C V^{3} = 1/2 \times 1.23\times .4\times \(5.36)^{3} =37.88$

                                                                      =37.88 W/M²

2. POWER=$1/2\rho C V^{3}A = 1/2 \times 1.23\times .4\times \(5.36)^{3}\times 22/7\times 25 =2976.5 W$

SO, MAXIMUM EXTRACTABLE POWER =35% OF 2976.5W

                                                                      = 1041.79W
