Carry out the step$-$by$-$step simulation in the COCO simulator of the following problem:A solution of sugar in water will concentrate from $5\%$ by weight of sugar to $20\%.$ The solution, which is close to $45\backslash$deg C$,$ is continuously fed to a bubble column. Air at $45\backslash$deg C with a dew point of $4\backslash$deg C is bubbled through the column and emerges saturated. Air humidification can be considered adiabatic. Consider $1$ kg of solution at the column inlet.a$)$ What are the absolute humidities of the inlet and outlet air?b$)$ How many kg of dry air must be fed for each kilogram of sugar solution introduced?c$)$ What is the corresponding volume in m$3$ of humid air that enters?
