Thank you, excellent explanation, I see you are calculating using theoretical stages, if I assume a tray efficienty of 0.5, that would be the double of trays right?
A trayed tower operating at 1 atm is to be designed to continuously distill 200 kmol/h (55.6 mol/s) of a binary mixture of 60 mol% benzene, 40 mol% toluene. A liquid distillate and a liquid bottoms product of 95 mol% and 5 mol% benzene, respectively, are to be produced. Before entering the column, the feed-originally at 298 K-is flash-vaporized at 1 atm to produce an equimolar vapor liquid mixture (VF/p=L/p= 0.5). A reflux ratio 30% above the minimum is specified. Calculate: (a) The quantity of the products. b) The minimum number of theoretical stages. (c) The minimum reflux ratio. (d) The number of equilibriumn stages and the optimal location of the feed stage for the reflux ratio specified. Could you please solve this problem?
what if we dont know the tube diameters in advance. We have to select some size from a table based on the optimal velocites and flow areas based on the given flow rates?
Excellent video. What about the elbows? Are they short radius or long radius? In my 42 years in the business, I’ve seen more hydronic inefficiencies due to the use of short radius elbows. It seems like most engineers just don’t get it.
Thank you very much for this video. however i still have a question. How to obtain the operating volume flow using the standard volume flow when the medium is water vapour?
Many thanks for your video. I tried the same thing with 3 factors (two levels) with 8 experiments (full factorial 2^3 Design) yet the model values are the same as the response values. What does that mean?
thanks mister. Just a suggestion. please put up a pointer/cursor when you are talking about anything paticular in your slides. I got confused many times, had to spend 1 and a half hour for this
