A Process Control Question You see a transfer equipment consisting of two tanks. The heat of the inner tank is transferred by convection along the wall. -The volume of each tank; V= 1m -Heat transfer cross-sectional area, A= 1m Flow of heat between tanks heat transfer coefficient ha= 10 cal/h(m) C Heat capacity between each tank C: 2 cal/kg (C) The temperature of the steam fed to the tank and the temperature inside the tank are initially equals. PID controller is used in the process when a change in heat flow to the inner tank occurs to keep the tank exit temperature (T) at the set value. Write transfer functions. Please show the calculations step by step.
