 Q1 (6marks): A pressure measuring device has an initial pressure reading

Q1 (6marks): A pressure measuring device has an initial pressure reading Pm=12% has been subjected to a step change of magnitude 2 in its input (Pin). The device output response exhibits an underdamped second order pressure response. An oscillation response is obtained with two successive peaks of 27 pressure \% and 20 pressure \% occurring at times (time 1) and (time 2) minutes after the change. The new steady state pressure reading is 18 pressure %. a) Find the device T.F Pm(s)/Pin(s). b) Write the pressure response and sketch it. c) Determine the period of oscillation, angular frequency, and overshoot % Q2 (4marks): Two interacted liquid level tanks, each has resistance of Rsec/m2 and crosssectional area 1m2, subjected to a unit step in feed flow rate, find the response of tank two and sketch it
