Determine the highest daily domestic water consumption and the total domestic water consumption for this city (using a standard value of 0.15 m3/day per person for domestic water consumption, and 0.20 m3/day per person for total domestic water consumption; the penetration rate of tap water is 90%). Answer: (1) Maximum daily domestic water consumption for residents: 50,000*0.15*90% = 6,750 m3 (2) Maximum daily total domestic water consumption for residents: 50,000*0.2*90% = 9,000 m3
(1) 6750m3 ； (2), 9000m3
75000M3 90000M3
(1) Maximum daily domestic water consumption for residents: 50,000 × 0.15 × 90% = 6,750 m3 (2) Maximum daily total domestic water consumption for residents: 50,000 × 0.2 × 90% = 9,000 m3
(1) Maximum daily domestic water consumption: 500000*0.15*90% = 67500 m3 (2) Total domestic water consumption: 500000*0.2*90% = 90000 m3
Residential domestic water consumption: 50,000 × 0.15 × 90% = 6,750 m3； ； Total domestic water consumption: 50,000 × 0.2 × 90% = 9,000 m3
(1) Maximum daily domestic water consumption: 500000*0.15*90% = 67500 m3 (2) Total domestic water consumption: 500000*0.2*90% = 90000 m3
(1) Maximum daily domestic water consumption for residents: 500,000 X 0.15 X 90% = 67,500 m3 (2) Maximum daily total domestic water consumption for residents: 500,000 X 0.2 X 90% = 90,000 m3
(1) Maximum daily domestic water consumption for residents: 50,000 × 0.15 × 90% = 6,750 m3 (2) Maximum daily total domestic water consumption for residents: 50,000 × 0.2 × 90% = 9,000 m3
