a. Explanation Given: The volume of the blood is four liter which initial concentration is zero. This implies V = 4 L . The blood contains the concentration 500 m g / L with drug solution and the inflow rate of the blood is 0.06 L . That is, C i = 500 m g / L and R = 0.06 L . Calculation: The stirred tank reaction is computed as follows, m ′ ( t ) = − 0.06 4 m ( t ) + ( 500 ) ( 0.06 ) m ′ ( t ) = − 0.015 m ( t ) + 30 Rewrite the above differential equation as follows, m ′ ( t ) − 0.015 m ( t ) + 30 = 1 Integrate on both sides of the above expression with respect to t . That is, ∫ m ′ ( t ) − 0.015 m ( t ) + 30 d t = ∫ 1 d t − 1 0.015 ∫ 0.015 m ′ ( t ) d t 0 b. To determine To find: The initial value problem of the given function and graph the solution for both the mass of the drug and the concentration of the drug. c. To determine To find: The steady state mass of the drug in the blood. d. To determine The time in which the drug mass reach 90 % of steady state level.
