Calculate how many liters and gallons of water are wasted in
Calculate how many liters (and gallons) of water are wasted in 1 month by a toilet that leaks 2 drops of water per second. (1 liter of water equals about 3,500 drops and 1 liter equals 0.265 gallon.) How many bathtubs (each containing about 151 liters or 40 gallons) could this wasted water fill? Let\'s assume you are a government regulator charged with drawing up plans for controlling water pollution. Briefly describe one idea for controlling water pollution from each of the following sources: an effluent pipe from a factory going into a stream, a parking lot at a shopping mall bordered by a stream, a farmer’s field on a slope next to a stream, and the lawns around the homes located next to the stream or lake.
Solution
The toilet leakes 2 drope in 1 second
In 1 hour drops of water wasted = 60*60*2 = 7200 drops
In one day drops of water wasted = 24*7200 = 172800 drops
Lets say its a 31 day month we are dealing with , then the number of drops of water wasted in 1 month = 31*172800 = 5356800 drops
in 1 liter there are 3500 drops of water
=> 5356800 drops of water will have = 5356800/3500 = 1350.514 L of water
and in 1 liter there is .265 gallons of water
then in 1350.415 L of will have = 1350.415*.265 = 405.586 gallons of water
hence in 1 month 1350.514 L(405.586 gallons) of water is wasted in 1 month from a leaking toilet.
1 bathtub contains 151 liters of water
=> 1350.514 L of warer will fill = 1350.514/151 = 8.944 = 9 bathtubs
an effluent pipe from a factory going into a stream
the effluent shall go through the effluient treatment plant before it goes into the steram. So that is could be treated in order to get rid of the harmful chemicals and pollutans.
a parking lot at a shopping mall bordered by a stream
We\'ll design a wall in order to stop the gasoline or any other fluid coming out of the cars in case there is a spillage from the vehicle . This wall will ach as an barrier between land and water and no fluid would go into the water stream .
a farmer’s field on a slope next to a stream
the waste coming form the field shall go to recycling station where all the solid pollutants will be removed and then the treated water will go into the stream.
the lawns around the homes located next to the stream or lake
THe lawns will have a efficient sewer system that will take the waste water from the lawns to the nearst effluent treatment plant.
