From the calculation, we can infer that the amount of water saved by the efficient washer is less than the average person's consumption in the average span of life.
<h3>What is efficiency?</h3>
The ratio of useful output to total input can be used to calculate efficiency.
A typical washing machine uses 41 gallons of water every load, whereas a highly efficient washing machine uses less than 28 gallons.
Suppose an average person lives for 80 years. The total number of days will be:
80×365 = 29200 days.
1. We assume that daily once the washer is used. So total water saved during year time:
28×365 = 10220 Gallon of water is saved.
2. In 1-day, the average person drinks 8 glasses which is equivalent to 2 quarts of water & there are 4 quarts in a gallon which imply that a person drinks half a gallon of water per day.
So, in a lifetime the person will drink:
29200(days)×0.5(gallons) = 14600 Gallon
Hence, from the above calculation, we can infer that the amount of water saved by the efficient washer is less than the average person's consumption in the average span of life.
