Equipment was Forced circulation evaporator $,$feed $3\%$ sodium nitrate solution and output $2200$liter per hour of condensed water and sodium nitrate crystal, Inputs are heat $115$ degree celcious temperature vacuum of $700$mmWc was provided, For cooling $200$TR chiller was provided $,$ please implement the following in a step$-$by$-$step manner:

$1.$ Identify the control variables, manipulated variables, and the disturbance

variables.

$2.$ Try to develop a dynamic model of the system using material and energy

balance equations. You can do some literature review to directly obtain the

already existing models corresponding to your work domain by searching a few

research articles.

$3.$ Perform degrees of freedom analysis.

$4.$ Develop a transfer function model to correlate the control variable $($output$)$

with the manipulated and disturbance $($input$)$ variables.

$5.$ Identify if it is a first order$/$ second order model.

$6.$ Consider unit step, ramp, and impulse inputs and identify the response of the

output control variable in time domain.
