Dynamic Simulation in Chemical Engineering


Dynamic simulation is an extension of steady-state process simulation whereby time-dependence is built into the models via derivative terms i.e. accumulation of mass and energy. The advent of dynamic simulation means that the time-dependent description and control of real processes in real or simulated time are possible. This includes the description of starting up and shutting down a plant, changes ... Read More »

How the Centrifugal Force Generated in the Centrifugal Pump?

centrifugal pump

Answer: – The process liquid enters the suction nozzle and then into the eye (center) of the revolving device known as an Impeller. When the impeller rotates, it spines the liquid sittings in the cavities between the vanes outward and provides centrifugal acceleration. As the liquid leaves the eye of the impeller alow – pressure area is created causing more liquid ... Read More »
