At a certain location, wind is blowing steadily at 7 m/s. Determine the mechanical energy of air per unit mass and the power gen
Kaylis [27]

Answer:

Explanation:

From the information given;

The velocity of the wind blow V = 7 m/s

The diameter of the blades  (d) = 80 m

Percentage of the overall efficiency \eta_{overall} = 30\%

The density of air \rho = 1.25 kg/km^3

Then, we can use the concept of the kinetic energy of the wind blowing to estimate the mechanic energy of air per unit mass by using the formula:

e_{mechanic} = \dfrac{mV^2}{2}

here;

m = \rho AV

= 1.25 \times \dfrac{\pi}{4}(80)^2 \times 7

= 43982.29 kg/s

∴

W = e_{mechanic} = \dfrac{mV^2}{2}

= \dfrac{43982.29 \times 7^2}{2}

= 1077566.105 \ W

\mathbf{ =1077.566 \ kW}

The actual electric power is:

W_{electric} = \eta_{overall} \times W

W_{electric} = 0.3 \times 1077.566

\mathbf{W_{electric} =323.26 \ kW}

Consider a system with two tasks, Task1 and Task2. Task1 has a period of 200 ms, and Task2 has a period of 300 ms. All tasks ini
Murrr4er [49]

<u>Explanation:</u>

Task 1 time period = 200ms, Task 2 time period = 300ms

Task ticked = \frac{1000ms}{200ms}= 5  →  5 times

Task 2 ticked =\frac{1000ms}{300ms} = 3.33 → 3 times

At 600 ms → 200ms 200ms 200ms

                     300ms → \frac{30ms}{60ms}

Largest time period = H.C.M of (200ms, 300ms)

                                 = 600ms
