A company is developing a new biofuels process. It needs to improve its process control model for a distillation column. When the column reflux condenser is operated with a steady$-$state flow of cooling water of $4\mathrm{.}0$ m$3/$min$,$ the liquid level in the condenser is at $0\mathrm{.}8$ m$.$ When an operator rapidly changes the cooling water flow rate to $4\mathrm{.}4$ m$3/$min $($step change$),$ the following liquid level values in the reflux condenser are observed:

Time, min Liquid level, m

$00\mathrm{.}8$

$61\mathrm{.}0$

$101\mathrm{.}4$

$162\mathrm{.}0$

$222\mathrm{.}6$

$323\mathrm{.}0$

$422\mathrm{.}8$

$502\mathrm{.}5$

$562\mathrm{.}3$

$782\mathrm{.}3$

$862\mathrm{.}4$

a$.$ Advise the management of what is the simplest transfer function to describe the dynamics of the reflux condenser $($dependence of the reflux liquid level on the cooling water flow rate$)$:

Explain your recommendation. obtain parameters for your proposed transfer function with regression analysis using all the data points with excel solver. Report the obtained parameter values and their units. Report the values with one decimal place accuracy. Build a simulink model of this on MATLAB
