There's a tank containing 50 L of a solution into which 10 g of salt is dissolved in. A solution that contains 2g/L of salt flows into the tank at a rate of 4L/min and the well stirred mixture flows out at a rate of 2L/min. Find the following. What is the concentration of salt in the tank after 30 mins?
Oil flows at a constant rate of 10L/min into a tank that can hold 40L of liquid. Initially the tank held 20 L of brine solution, which dissolved 2kg of salt. The solution inside the tank is kept well stirred and flows out of the tank at a rate of 8 L/min. Find the amount of salt in the tank when the tank is full.
a tank contains 50kg 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 9L/min. The solution is mixed and drains from the tank at the same rate. what is the concentration of our solution in the tank initially concentration = ? (kg/L) find the amount of salt in the tank after 3 hours. amount = ? kg c) Find the concentration of salt in the solution in the tank as time approaches infinity. concentration = ? (kg/L)
A tank holds 300 gal of brine solution with 50 pounds of dissolved salt. A brine solution containing 2 lbsalt/gal is pumped into the tank at a rate of 3 gal/min and the solution inside the tank is also the pumped out at the same rate, estimate the amount of the salt dissolved in the tank after a long time.
A brine solution of salt flows at a constant rate of 8 L/min into a large tank that initially held 100 L of brine solution in which was dissolved 0.2 kg of salt. The solution inside the tank is kept well stirred and flows out of the tank at the same rate. If the concentration of salt in the brine entering the tank is 0.04 kg/L, determine the mass of salt in the tank after t min. When will the concentration of salt in the tank reach 0.01 kg/L? Determine the mass of salt in the tank after t min. mass 4-4e 2t 25 kg
