Salt water flows at a constant rate of 6 L/min into a tank that initially held 100 L of salt solution in which was dissolved 0.5 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 solution entering the tank is 0.05 kg/L. a) Determine the mass of salt in the tank after t min. b) When will the concentration of salt in the tank reach 0.03 kg/L? a) Determine the mass of salt in the tank after t min. mass= kg b) When will the concentration of salt in the tank reach 0.03 kg/L? The concentration of salt in the tank will reach 0.03 kg/L after minutes. (Round to two decimal places as needed.)

Question
Transcribed Image Text:Salt water flows at a constant rate of 6 L/min into a
tank that initially held 100 L of salt solution in which
was dissolved 0.5 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
solution entering the tank is 0.05 kg/L.
a) Determine the mass of salt in the tank after t min.
b) When will the concentration of salt in the tank
reach 0.03 kg/L?
a) Determine the mass of salt in the tank after t min.
mass= kg
b) When will the concentration of salt in the tank
reach 0.03 kg/L?
The concentration of salt in the tank will reach 0.03
kg/L after minutes.
(Round to two decimal places as needed.)
