A tank, containing 1260 liters of liquid, has a brine solution entering at a constant rate of 4 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 700 70 kg/L. Determine the amount of salt initially present within the tank. Initial amount of salt: = 18 kg help (numbers) 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 help (formulas) Book: Section 1.4 of Notes on Diffy Qs
