Answer:
2667 tires are needed to meet the demand of ten homes for one year.
Explanation:
According to the Second Law of Thermodynamics, only a part of generated energy when tires are burned can be utilized due to irreversibilities associated with finite temperature differences. The energy from a tire that can be transformed into electricity (), measured in kilowatt-hours, is estimated by definition of efficiency:
Where:
- Efficiency, dimensionless.
- Energy liberated by burning, measured in kilowatt-hours.
Given that and , the amount of energy per year generated by a tire is:
Now, the amount of tires needed to meet the demand of then homes for one year is:
2667 tires are needed to meet the demand of ten homes for one year.
