An electrically heated process is known to exhibit second-order dynamics with the following parameter values: k, 3°ckw1, r 4 min, 0.5. the process initially is at steady state at 50°c with heater input of 20 kw determine the required heater input in order to increase the process (a) temperature to 80°c. (3 marks) (b) determine the maximum temperature of the resulting response and the time required to reach its first maximum value. 8 marks) plot the process temperature as a function of time and state the important (c) characteristics (10 marks) explain the significance of the damping coefficient in the response of a second (d) order process to a step input. 4 mark lemical nlant
