Refer to Figure 7.10.1. Assume that the resistances obey the linear relation, so that the mass flow q1 through the left-hand resistance is q1 = (p1 - p)/R1, with a similar linear relation for the right-hand resistance.
a. Create a Simulink subsystem block for this element.
b. Use the subsystem block to create a Simulink model of the system discussed in Example 7.4.3 and shown in Figure 7.4.3a. Assume that the mass inflow rate qm1 is a step function.
c. Use the Simulink model to obtain plots of h1(t) and h2(t) for the following parameter values: A1 = 2 m2, A2 = 5 m2. R1 = 400 l/(m.s), R2 = 600 l/(m.s), ( = 1000 kg/m3, qmi = 50 kg/s, h1(0) = 1.5 m. and h2(0) = 0.5 m.
