(c) New York's department of health recommends that salt concentration should not exceed 0.02 g/liter for the water to be drinkable. Given that, initially the sea water contains 35 g/liter liters of salt. You keep measuring the amount of salt in the tank and note that after a while it is no longer changing significantly. What is the amount of salt now ? Calculate the salt concentration and comment on whether the water in the tank is safe to drink.

Transcribed Image Text:You have a shortage of drinkable water in your town and are trying to prepare
safe drinking water by mixing river water with concentrated sea water. A tank
initially has So amount of salt mixed in 1000 liters of water in it. River water
enters the tank at a rate of r liters/h and the salt concentration of this water
is 0.01 g/liter. Assume that the water salt mixture is well-stirred. It is also
given that water is drained from the tank at the same rate as it comes in.
