105300 gallons of water are used in a year.
What is Flow rate?
The volumetric flow rate is the volume of fluid which passes per unit time; usually it is represented by the symbol Q.
Here given flow rate = 1.5 gallons
water consumed in 1 shower of 15 minutes = 1.5×15=22.5
Number of minutes spent in the shower in a week = 15×6=90
Gallons used per week = 22.5×90=2025
There is 52 weeks in a year.
52×2025 = 105300
Thus, 105300 gallons of water are used in a year.
