Process Control and Instrumentation In a closed loop system, the process to be controlled is an integrating process with transfer function l/2s. The controller proposed to be used in an integral controller with transfer function 1/T₁s. When a step change in set point is applied to such a closed loop system, the controlled variable will exhibit Underdamped response Undamped response Overdamped response Unstable response Underdamped response Undamped response Overdamped response Unstable response ANSWER DOWNLOAD EXAMIANS APP
Process Control and Instrumentation Temperature control of an exothermic chemical reaction taking place in a CSTR is done with the help of cooling water flowing in a jacket around the reactor. The types of valve and controller action to be recommended are Air to open valve with the controller direct acting Air to open valve with the controller indirect acting Air to close valve with the controller indirect acting Air to close valve with the controller direct acting Air to open valve with the controller direct acting Air to open valve with the controller indirect acting Air to close valve with the controller indirect acting Air to close valve with the controller direct acting ANSWER DOWNLOAD EXAMIANS APP
