Tanks T1 and T2 have 75 gal and 125 gal of salt solutions. A solution with 3 pounds of salt per gallon is pumped into  T1  from an external source at 1 gal/min, and a solution with 4 pounds of salt per gallon is pumped into T2 from an external source at 2 gal/min. The solution from T1 is pumped into T2 at 3 gal/min, and the solution fromT2 is pumped into T2 at 4gal/min. T1 is drained at 2 gal/min and T2 is drained at 1 gal/min. Let Q1(t) and Q2(t) be the number of pounds of salt inT1andT2, respectively, at time t>0. Derive a system of differential equations forQ1andQ2. Assume that both mixtures are well stirred. you don't need to solve the system

Question

Tanks T1 and T2 have 75 gal and 125 gal of salt solutions. A solution with 3 pounds of salt per gallon is pumped into  T1  from an external source at 1 gal/min, and a solution with 4 pounds of salt per gallon is pumped into T2 from an external source at 2 gal/min. The solution from T1 is pumped into T2 at 3 gal/min, and the solution fromT2 is pumped into T2 at 4gal/min. T1 is drained at 2 gal/min and T2 is drained at 1 gal/min. Let Q1(t) and Q2(t) be the number of pounds of salt inT1andT2, respectively, at time t>0. Derive a system of differential equations forQ1andQ2. Assume that both mixtures are well stirred. you don't need to solve the system
