Question: A pneumatic system defined by a resistance Rg and capacitance Cg is subjected to a ramp input pressure pi(t) = Pit, where Pi is a constant. After a time t1 = 3s, it is determined that the output pressure is twice the input pressure constant pi. Use the transfer function approach to determine the system's time constant. For a pressure pi = 50 atm and zero initial conditions, plot the output pressure as a function of time.
