Below are the readings that we got from a temperature sensor. The sensor was at 19°C initially and was introduced into a fluid at 80°C. Temperature in Time in degrees C seconds 19 0 57 1 69 2 73 3 75 77 78 79 79,6 8 79,8 9 80 10 We will approximate the temperature sensor by a first order process. a) Use the provided data above to provide the equation of the first order process in the time domain. In particular calculate the time constant. b) Plot on the same diagram the measured temperatures and the estimated ones from the equation you found in a).
