Hi, i might try to help and answer you question. If we look at the equation for Upper Operating Line in McCabe-Thiele method, you would notice that its slope (gradient) is determined by reflux ratio, as R got larger the slope gets steeper, there is less chance of creating a "bounce" or more horizontal line because the vertical line has to travel further down before eventually bounce and create a horizontal line. So generally, the less the space between the VLE curve and the operating lines , the more likely it is to form more stages and vice versa
If it is given in the question that the feed is entering with 70% vapour, then 30% will be liquid. Hence in this you can take q=30/100 that is 0.3 All the best to you !
thanks a lot for your help I was stuck to similar kind of problem since morning and found your channel while browsing through a tons of videos!! But your video helped a lot.. keep up doing this amazing work!!!
In this problem you can apply this. Better watch the part 2 video given link in the description, It contains everything about the value of q and the q-line.
Seal School I see. I have an exam in four days and your videos are helping me a lot. Can you talk about optimum Reflex, Plate and Column Efficiency, and Azeotropic Distillation? Thanks in advance.
