Answer:
a. 30.O7A
b. no reading
Explanation:
for the first load with power factor 0.8, we calculate the reactive power
note the reactive power is calculated as
where p=power
a. for the first load the reactive power is
for the second load the reactive power is
The total reactive power is the summation of both reactive power in he load
and the total real power is 25kw
Hence using Pythagoras theorem to calculate the apparent power we have
Hence we can determine the source current using
b. in a balance 3phase system, there is no neutral current, Hence the ammeter will read zero current
Answer:
Acceleration of the car at t = 5 secs is
Explanation:
The position of the car as a function of time is represented as
Now by definition of acceleration we have
Applying the value of x(t) we obtain acceleration as follows
Answer:
Gross building area
Explanation:
The Gross building area refers to the entire area of a building covering all the floors. The measurement is expressed in square feet. The Gross building area also includes basements, penthouses, and mezzanines. It is calculated by estimating the exterior dimension of the building. Storage rooms, laundries, staircases are also a part of the gross building area.
