Noisy data for the step response of a boiler temperature T to a decrease in air flow

Question:

Noisy data for the step response of a boiler temperature T to a decrease in air flow rate q from 1000 to 950 cfm are shown below. Develop a FOPTD model using a method from Chapter 7. Be sure to use deviation variables and report units for the model parameters.

Table E7.10 q (cfm) T (°C) t (min) 1000 849 1000 851 1000 850 950 851 4 950 849 950 860 950 867 873 950 878 950 950 882
