During a one year time period, how many gallons of water would the average household save by using an efficiency washer vs a regular washer? Is this one year savings more or less than the amount of water an average person drinks in a lifetime? Explain and show your assumptions, calculations, and conversions.

The given data is, As per U.S. Environmental Protection Agency (EPA) states that a standard washing machine uses 41 gallons of water per load, but a highly efficient washing machine uses less 28 gallons of water per load.Say a person clothes in an year can be washed in 3 times per week ( for a full load) So, the total number of loads that he puts his clothes to wash is (52*3) = 156 He washes his clothes 156 times in an year Some of the normal washing machines uses 20 gallons of water per load So, total number of water used for washing is 156*20= 3120 gallons of water Hence, by using an ordinary washing machine the total amount of water put to ise is 3120 gallons per year Generally, a high energy efficient machines useson an verage 14 gallons of water per load So, water used here is equal to 14*156= 2184 gallons Hence, savings in water between a normal and energy efficient machine is given by the difference of the both Difference = 3120-2184= 936 gallons Hence, by using an energy efficient machine, water saves is of the order 936 gallons per year 2) Say the average water drunk by a person per day is equal ro 4 liters Water drunk in 1 year = 365*40= 1460 liters epd year Average life expectancy = 70 years So, total water drunk = 70*1460= 102200 liters 1 liter = 0.264 gallon Water = 102200*0.264= 26998.38 gallons Hence, water saved in 1 year is not greater than water drunk by a person in life time 3) Hence from the above calculation we can infer that the amount of water saved by the efficiency washer is less than the average person consumption in the average span of life.
