A tank, containing 1520 liters of liquid, has a brine solution entering at a constant rate of 3 liters per minute. The well-stirred solution leaves the tank at the same rate. The concentration within the tank is monitored and found to be c(t) = e(-t/800)/80  kg/L. Determine the amount of salt initially present within the tank. Initial amount of salt = ? kg. Determine the inflow concentration cin(t), where cin(t) denotes the concentration of salt in the brine solution flowing into the tank. cin(t) = ? kg/L

Question

A tank, containing 1520 liters of liquid, has a brine solution entering at a constant rate of 3 liters per minute. The well-stirred solution leaves the tank at the same rate. The concentration within the tank is monitored and found to be

c(t) = e(-t/800)/80  kg/L.

Determine the amount of salt initially present within the tank.

Initial amount of salt = ? kg.

Determine the inflow concentration cin(t), where cin(t) denotes the concentration of salt in the brine solution flowing into the tank.

cin(t) = ? kg/L
