The person's average power when he uses an energy equivalent to 50 bbl of crude oil in one year is 3.49×10⁴ kW.
What is average power?
Average power can be defined as the total work performed to the total time it takes to perform the work.
To calculate the average power consumption of the person, we use the formula below.
Formula:
P = E/t............ Equation 1
Where:
- P = Average power
- E = Total energy
- t = Time
From the question,Given:
E = 50×6.12×10⁹ J = 3.06×10¹¹ J
t = 1 year = (365×24) days = 8760 seconds
- Substitute these values into equation 1
P = 3.06×10¹¹/8760
P = 3.49×10⁴ kW
Hence, the average power is 3.49×10⁴ kW.
