Problem 12.5

A process stream is heated using a shell and tube heat exchanger. The exit temperature is controlled by adjusting the steam control valve shown in Fig. E12.5. During an open-loop experimental test, the steam pressure Ps was suddenly changed from 18 to 20 psig and the temperature data shown below were Exercises 233 Steam Figure E12.5 obtained. At the nominal conditions, the control valve and current-to-pressure transducers have gains of Kv = 0.9 psi/psi and K1p = 0.75 psi/rnA, respectively.
