Question

Береги воду! на время когда чистишь зубы выключай воду чтобы ополостнуть рот достаточно одного стакана воды старайся плотно закрыть кран если из крана капает вода то из него за сутки может вытечь 24 л воды сколько литров воды можно сэкономить за неделю если хорошо закрывать кран

Answer 1

В один день мы чистим зубы 2 раза :
2•7=14(раз) мы чистим зубы за неделю .
24•7=168(литров) может вытечь из крана за неделю если плотно кран не закрывать .
Предположим , 1 стакан -0,5 (1/2) .
7•0,5(1/2) = 7/1(семь первых)•1/2(одна вторая ) =3,5 литров если плотно закрывать кран
168-3,5=164,5(литров)
Ответ:164,5 литров можно сэкономить.

Water Conservation Tips

Conserving water is an important practice that helps protect our environment and ensure the availability of clean water for future generations. One simple way to conserve water is by turning off the tap while brushing your teeth. Let's calculate how much water can be saved in a week by following this practice.

Water Usage Calculation

To calculate the amount of water that can be saved by turning off the tap while brushing teeth, we need to consider the average flow rate of a tap and the duration of brushing.

According to the United States Environmental Protection Agency (EPA), the average flow rate of a bathroom faucet is around 2.2 gallons per minute (GPM) or approximately 8.3 liters per minute (LPM) [[1]]. Let's assume that a person brushes their teeth for 2 minutes each time.

By turning off the tap while brushing, we can save 8.3 liters of water per minute. Therefore, by brushing for 2 minutes, we can save 16.6 liters of water each time.

Water Leakage Calculation

Now, let's consider the water leakage from a tap. If a tap is left dripping and each drip releases one milliliter of water, it would take 1,000 drips to make one liter. Therefore, if a tap drips continuously for 24 hours, it can waste 24 liters of water in a day.

Water Savings in a Week

Assuming that the tap drips continuously for 24 hours, we can calculate the amount of water wasted in a week.

24 liters of water wasted per day x 7 days in a week = 168 liters of water wasted in a week.

By turning off the tap while brushing teeth and ensuring it is tightly closed to prevent any leakage, we can save 16.6 liters of water each time we brush. If we brush twice a day, we can save:

16.6 liters of water saved per brushing x 2 brushings per day = 33.2 liters of water saved per day.

Therefore, by following these water conservation practices for a week, we can save:

33.2 liters of water saved per day x 7 days in a week = 232.4 liters of water saved in a week.

Conclusion

By turning off the tap while brushing your teeth and ensuring it is tightly closed to prevent any leakage, you can save a significant amount of water. Following these practices can help conserve water and contribute to a more sustainable future.

Remember, every drop counts!
