Question: 4.15 An electrically heated process is known to exhibit second-order dynamics with the following parameter values: K=3C/kW,=3min,=0.7. If the process initially is at steady state

4.15 An electrically heated process is known to exhibit second-order dynamics with the following parameter values: K=3C/kW,=3min,=0.7. If the process initially is at steady state at 70C with heater input of 20kW, and the heater input is suddenly changed to 26kW and held there. (a) What will be the expression for the process temperature as a function of time? (b) What will be the maximum temperature observed? When will it occur
