Explanation

In a closed-loop control system, feedback from the controlled variable is continuously compared to the desired setpoint, and adjustments to the manipulated variable are made to maintain the desired process conditions.

Which parameter is used to characterize the flow behaviour of a fluid in laminar and turbulent flow regimes? In a reversible exothermic reaction, what effect does increasing the temperature have on the equilibrium conversion? What is the driving force for mass transfer in a binary gas mixture undergoing diffusion? According to the first law of thermodynamics, what is the mathematical expression for the change in internal energy of a system undergoing a process?
