Question: An electrically heated process is known to exhibit second-order dynamics with the following parameter values: K = 3 C/kW, T = 3 min,~ = 0.7.

An electrically heated process is known to exhibit second-order dynamics with the following parameter values: K = 3 C/kW, T = 3 min,~ = 0.7. If the process initially is at steady state at 70 oc with heater input of 20 kW and the heater input is suddenly changed to 26 kW 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?
