n the bottom of a Stefan tube there is a quiescent liquid with a mixture of acetone (component 1) and methanol (component 2). Vapor that evaporates from this pool of liquid diffuses to the top of the tube. Air (component 3) keeps the mole fractions of components 1 and 2 equal to zero. This... Platforms: Matlab

***Note***This method of using units is quick and clean. For a more complete version that automatically does dimensional analysis, see the file entitled "Units and Dimensions Suite for Matlab" (See the Acknowledgements section below)*******The units.m function returns a struct containing the SI...

CompPad is an OpenOffice.org extension that provides live mathematical and engineering calculations within a Writer document. It is intended to provide a free / open-source alternative to Mathcad . Platforms: Windows, Mac, Linux

We use the SRK equation of state to compute the correction factor due to gas-phase nonideality as a result of the high pressure applied in the ammonia synthesis. We also compute the extent of reaction. Plots of these two quantities versus pressure for temperature equal to 800K are presented. The... Platforms: Matlab
