3. A bankrupt chemical firm has been taken over by new management. On the property they found a 20000 m' brine pond containing 25000 mg/L of salt. The new owners propose to flush the pond into their discharge pipe leading to the Atlantic Ocean, which has a salt concentration above 30000 mg/L. What flow rate of freshwater (m'/s) must they use to reduce the salt concentration in the pond to 500 mg/L within one year?

Landfills

The landfill is a site used for the disposal of waste materials. The landfill is a solid waste facility that is often known as a dumping ground. The image below shows a landfill site in Hawaii. Landfilling is the most ancient and common method used for the disposal of waste. For the landfill, a deep trench is constructed in an isolated place away from the city. The trench for landfills is designed properly after analyzing the total population and the waste generation per capita. The waste is dumped into the trench and after every layer of waste, a layer of soil is spread on the top of it.
