Question

Tanks T1 and T2 both initial contains 50 gallons of pure water. Starting at t = 0, water that contains 1 pound of salt per gallon is poured into Ti at a rate of 2 gal/min. The mixture is drained from T1 at the same rate into the second tank T2. Starting at to = 0, a mixture from another source that contains 2 pounds of salt per gallon is poured into T2 at a rate of 2 gal/min. The mixture is drained from T2 at a rate of 4 gal/min. (a) find a differential equation for the quantity Q(t) of salt in tank T2 at timet>0 (b) Solve the differential equation in the previous part (c) find lim t→oo Q(t)
