Question

A hot liquid is cooled by cold water in a counter-currentheat exchanger: shown in fig Temperature Tₕ₂ is to be controlled by adjusting flow rate,w꜀.The temperature sensor/transmitter (TT) is direct-acting.Based on safety considerations, should the control valve beair-to-open or air-to-close? Should the feedback controller bedirect-acting or reverse-acting?
