An electronic PID temperature controller is at steady state with an output of 12 mA. The set point equals the nominal process temperature initially. At t = 0, the set point is increased at the rate of 0.5 mA/min (equivalent to a rate of 2°F/min). If the PID transfer function and current settings are: P'(s) E(s) Kc = 2 (dimensionless) tl = 1.5 min = X=[1+=+=+=0] Kc1+ +T T,S TDS TD = 0.5 min (a) Derive an expression for the controller output p(t). (b) Repeat (a) for a PI controller. (c) Plot the two controller outputs in Simulink and qualitatively discuss their differences.

Safety considerations dictate that at a temperature of 320 K the liquid must occupy no more that 75 percent of the total volume of the vessel. For these conditions, determine the mass of the vapour in the vessel using the Redlich-Kwong equation of state. At 320 K the vapour pressure of propane is 16.0 bar.

The dynamic behavior of a pressure sens or/transmitter can be expressed as a first-order transfer function (in deviationvariables) that relates the measured value Pm to the actual pressure,P: P′m(s)/P′(s)=1/(30s+1). Both Pm and P have units of psi and the time constan t has units of seconds. Suppose that an alarm will sound if pm exceeds 45 psi. If the process is initially at steady state(Pm=P=35 psi),and then P suddenly changes from 35 to 50 psi at 1:30 PM, at what time will the alarm sound?
