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

the AADT for a section of suburban freeway is 150000 veh/day. Assuming this is an urban radial facility, what range of direction

igomit [66]

Answer:

design hour volumes will be 4000 to 6000

Explanation:

given data

AADT = 150000 veh/day

solution

we get here design hour volumes that is express as

design hour volumes = AADT × k × D ..............1

here k is factor and its range is 8 to 12 % for urban

and D is directional distribution i.e traffic equal divided by the direction

so here design hour volumes will be 4000 to 6000
