A tank contains 60 kg of salt and 2000 L of water. A solution of a concentration 0.015 kg of salt per liter enters a tank at the rate 6 L/min. The solution is mixed and drains from the tank at the same rate. a.) What is the concentration of our solution in the tank initially? concentration = (kg/L) b.) Find the amount of salt in the tank after 2.5 hours. amount = (kg) c.) Find the concentration of salt in the solution in the tank as time approaches infinity. concentration = (kg/L)

Step 1
So, the initial concentration is 60 kg / 2000 L = 0.03 kg/L. b) The rate of salt entering the tank is 0.015 kg/L * 6 L/min = 0.09 kg/min. The rate of salt leaving the tank is the concentration of salt in the tank times the rate of water leaving the tank. This is Show more…

A tank contains 50 kg of salt and 1000 L of water. A solution of a concentration 0.025 kg of salt per liter enters a tank at the rate 10 L/min. The solution is mixed and drains from the tank at the same rate. (a) What is the concentration of our solution in the tank initially? concentration = (kg/L) (b) Find the amount of salt in the tank after 2.5 hours. amount = (kg) (c) Find the concentration of salt in the solution in the tank as time approaches infinity. concentration = (kg/L)

A tank contains 60 kg of salt and 1000 L of water. Pure water enters a tank at the rate 6 L/min. The solution is mixed and drains from the tank at the rate 3 L/min. (a) What is the amount of salt in the tank initially? amount = _ (kg) (b) Find the amount of salt in the tank after 3.5 hours. amount = _ (kg) (c) Find the concentration of salt in the solution in the tank as time approaches infinity. (Assume your tank is large enough to hold all the solution.) concentration = _ (kg/L)
