Answer:
I = Line Current = 242.58 A
Q = Reactive Power = 41.5 kVAr
Explanation:
Firstly, converting 100 hp to kW.
Since, 1 hp = 0.746 kW,
100 hp = 0.746 kW x 100
100 hp = 74.6 kW
The power of a three phase induction motor can be given as:
where,
P in = Input Power required by the motor
V = Line Voltage
I = Line Current
Cosα = Power Factor
Now, calculating Pin:
a) Calculating the line current:
b) Calculating Reactive Power:
The reactive power can be calculated as:
Q = P tanα
where,
Q = Reactive power
P = Active Power
α = power factor angle
Since,
Therefore,
Answer:
amount of electric charge transported = 1.13 × C
Explanation:
given data
electric current = 237.0 mA = 0.237 A
time = 8 min = 8 × 60 sec = 480 sec
solution
we get here amount of electric charge transported that is express as
amount of electric charge transported = electric current × time ...........1
put here value and we get
amount of electric charge transported = 0.237 × 480
amount of electric charge transported = 113.76 C
amount of electric charge transported = 1.13 × C
(b) 75 kHz
(c) 80 kHz
(d) 160 kHz
(e) None of the above.
Answer:
Option D
160 kHz
Explanation:
Since we must use at least one synchronization bit, total message signal is 15+1=16
The minimum sampling frequency, fs=2fm=2(5)=10 kHz
Bandwith, BW required is given by
BW=Nfs=16(10)=160 kHz
Answer:
voltage across the capacitor's is 75 μF
Explanation:
given data
capacitor = 15 μF
voltage = 50V
dielectric constant k = 5
to find out
voltage across the capacitor's
solution
we will find here voltage across the capacitor's by this formula
voltage across the capacitor's = k
here k is 5 and = 15
put these value we get
voltage across the capacitor's = k
voltage across the capacitor's = 5 ( 15 ) = 75 μF
so voltage across the capacitor's is 75 μF
Answer and Explanation:
The computation is shown below
Total average cost + total variable cost = total cost
Let number of output be x
So,
Total fixed average cost = x × $30
Total variable cost = x × $15
Total cost = $2,500
Therefore,
$20 × x + $30 × x = $2,500
50 × x = $2,500
x = 50
Now the total variable cost is
= 50 × $20
= $1,000
And, the fixed cost is
= 50 × $30
= $1,500
