a. Use the subsystem block developed in Section 10.7 to construct a Simulink model of the system shown in Figure P30. The mass in flow rate is a step function.

b. Use the Simulink model to obtain plots of h₁(t) and h₂(t) for the following parameter values: A₁ = 3 ft², A₂ = 5 ft², R₁ = 30 ft^-1 ∙ sec^-1, R₂ = 40 ft^-1 ∙ sec^-1, ρ = 1.94 slug/ft³, q_mi = 0.5 slug/sec, h1(0) = 2 ft, and h₂(0) = 5 ft.
