Time delays (dead time)
Time between when a manipulated variable change is made
and when the actual output
change is measured
i.e.
delay between input and response
Ex:
-if there was a large pipe run between the mixing point
and the shower head à an input time delay (input dead time)
-if your body takes a while to detect a change in the
temperature of the stream
contacting your body àmeasurement dead
