Equilibrium Constants

The program computes the tie lines, the operating and mixing points and the number of equilibrium stages using the Hunter and Nash graphical method of a liquid-liquid extraction problem. One feed of acetic acid (35 wt %) in water which flow rate = 1000 kg/hr is extracted using a solvent...

This being a very basic program for the demonstration of bubble and dew point calculations of a ideal binary VLE mixture obeying Raoult's. The basic purpose of this program is to demonstrate VLE P-T-x-y calculations of a ideal binary mixture and to get related data in graphical form for any such...

The struct has two levels. The first level is the name of the constant. The second level has fields: "value", "uncert" and "unit".Example: phc = fundamentalPhysicalConstantsFromNIST(); phc.speed_of_light_in_vacuum.valuereturns 299792458and phc.speed_of_light_in_vacuum.unitreturns ms^-1Data was...

The program determines the constants Rmax and Km of the Michaelis-Menten model using data given in Fundamentals of Chemical Reaction Engineering by M. E. Davis & R. J. Davis, McGraw Hill, 2003. This data represents the substrate (catechol) concentration versus time. This data was obtained using...

One must input to a dialog box Antoine's constants, Wilson binary interaction parameters and liquid molar volume of any binary mixture of his choice. The program computes and plots activity coefficients, relative volatility and VLE diagram.


Platforms: Matlab

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,...

This m-file plots a NMR coupling diagram from coupling constants and number of splits (only 1/2-spin nuclei). Useful for educational purposes.Example: plotcoupling([8,2],[3,1])Produces a plot with the coupling constants 8 and 2 Hz, splitted three and one times, respectively.The screenshot is made...

This GUI accepts the various constants needed to run a Black-Scholes calculation for pricing several European options:Put, Call, Straddle, Strangle, Bull Spread, Bear Spread, ButterflyIt plots the pricing surface for the appropriate option and then runs a number of Monte Carlo simulations (d


Platforms: Matlab

The user has to provide the program the constants and parameters of the models using a dialog box. A pop-up menu and an update button allow the user to select the plot (Txy, activity coefficients and relative volatility).A similar program using Mathematica 6.0 is available at the following...
