Bell Curve Equation

This GUI uses a constant relative volatility (alpha) to estimate the equilibrium curve. From there, the GUI uses the "McCabe and Thiele Graphical Method" to estimate the ideal number of plates in the column.A reference is provided in the GUI: look in Help/About.Comments, suggestions or bugs,...
