In some chemical process operation, 4500kg/hr of pure liquid A is fed continuously to the first of a battery of two equal sized stirred tank reactors (cstr) arranged in series. Both theb reactors are maintained at the constant temperature. The consecutive reaction A--->(k1)B--->(k2)C takes place in the reactors. the values of specific reaction rate constants, k1 = 6 hr^-1 amd k2 = 3 hr^-1. the density of fluid is constant at 960 kg/m^3. calculate the size of the reactors that will offer the maximum yield of product B.
