Answer :
The calculated power is P = 3500 W. Power can be defined as the amount of work completed in a given amount of time.
Watt (W), which is derived from joules per second (J/s), is the SI unit of power. Horsepower (hp), which is roughly equivalent to 745.7 watts, is a unit of measurement sometimes used to describe the power of motor vehicles and other devices.
There are n = 140 students in the auditorium overall.
Each pupil is using a metabolic power of p = 125 W.
To keep the temperature in the auditorium consistent, the air conditioner's coefficient of performance (COP) is listed as 5.
Let P represent the required minimum amount of electric power to operate the air conditioner.The fact that
np = P in COP
P = np/COP
= ( 140 x 125 ) / 5
= 3500 W
