The current drawn by fluorescent lighting has a high total harmonic distortion. For this case, THD is calculated to be 88%. The

Alona [7]

Answer:

displacement power factor is 0.959087

Explanation:

given data

THD = 88%

true power factor = 0.72

solution

we get here total harmonic distribution THD is express as here

THD = $\sqrt{\frac{1}{g^2}-1}$ ..............1

her g is distortion factor

so put here value and we will get g that is

0.88² = $\frac{1}{g^2} -1$

solve it we get

g = 0.750714

and

displacement power factor is express as

DPF = $\frac{PF}{g}$ .................2

put here value and we will get

DPF = $\frac{0.72}{0.750714}$

DPF = 0.959087

Why would an aerospace engineer limit the maximum angle of deflection of the control surfaces?

WITCHER [35]

Answer:

You can create high drag which allows a steeper angle without increasing your air speed on landing. you can reduce the length of landing role. Flaps are also used to increase the drag they are retracted when they are not needed. it is adviseable to down he flaps during the time of take off.
