Let T=ABCD be a tetrahedron with the three plane angles at D all right angles, that is, ?ADB=?BDC=?CDA=90. (This is more explicitly known as a trirectangular tetrahedron.) Let ?=? CAD, ?=? CBD, ?=? ACB. Then cos ? =sin ? sin ?. The lines that join the ...

![Heat Transport and Chemical Reaction in Tubular Reactor with Laminar Flow
http://demonstrations.wolfram.com/HeatTransportAndChemicalReactionInTubularReactorWithLaminarF
The Wolfram Demonstrations Project contains thousands of free interactive visualizations, with new entries added daily.
This Demonstration shows the temperature and concentration profiles of an insulated tubular reactor in which a first-order, irreversible reaction AOverscriptBox[?, k]B takes place in a fluid undergoing laminar flow. Assuming that temperature does not af...
