Two tanks are arranged as shown in the attachment. Salt and water are added into the first tank at rates {see attachment}. The tanks are well mixed and the salt dissolves completely. The flow between the two tanks depends on the pressure difference {see attachment}. The flow out of te second tank is given by {see attachment}. Both flows are in m[cubed]/s of the solution in the respective tanks and you can assume that they are always positive. The tank areas are A1 and A2 respectively. Find the model of the system. The (two) outputs required are the density of the solution in each of the tanks.
