Well with finals coming we'd to learn the Ponchon-Savarit/enthalpy-concentration curve method for Unit Op. This method is used in the Distillation chapter to determine the number of theoretical trays needed with given specifications. I'm just gonna give a brief tutorial on how to use this graphical method. I'll do it via pictures, you may click to see the larger version.
I hope this is helpful in some way; it sure helped me to remember the method better haha :)
Feel free to correct/ask questions! Thank you :p
