The curve on the attached document shows the response of a bare thermocouple which has been subjected to a step change in temperature from 50 degrees celcius to 10 degrees celcius. Assuming that the bare thermocouple behaves as a single transfer lag system, determine the mathematical relationship between the temperature (T) and time (t). [ie determine the equation relating T to t].
