2. Early showerheads consumed either 5 or 7 gallons of water per minute (gpm). Federal plumbing standards (beginning with the Energy Policy Act of 1992) mandated that showerheads use no more than 2.5 gpm to conserve water and save (hot water) energy. High-efficiency showerheads use 1.5 or 1.75 gpm. An older showerhead (5 gpm) is used, on average, for 15 minutes. Determine the gallons of water used if the shower is used twice a day over a year (365 days). а. b. A high-efficiency showerhead (1.5 gpm) is used for 15 minutes. Determine the gallons of water used if the shower is used twice a day over a year (365 days).
