4.3 The dynamic behavior of a pressure sensor/transmitter can be expressed as a first-order transfer function (in deviation variables) that relates the measured value Pm to the actual pressure, P P(s)Pm(s)=30s+11 Both Pm and P have units of psi and the time constant has units of seconds. Suppose that an alarm will sound if Pm exceeds 45 psi. If the process is initially at steady state, and then P suddenly changes from 35 to 50 psi at 1:10 PM, at what time will the alarm sound
