Mathematical modeling for axial voidage distribution in CFB
Tutorials/exercises - 6 pages - Physics
Kwauk proposed that the characteristic fine particle distribution in fast fluidization could not be accounted for by the one-dimensional analysis on accelerative motion of particulate fluidization, and presented a physical model for a gas-solid fast fluidization system. The average solid...

Reactive distillation is the combination of separation and reaction ina single vessel. Today Reactive Distillation is discussed as a part of the broader area of reaction and separation, which comprises of many combination of chemical reaction with separation methods including distillation,...
Determination of outer sphere and total Chloride content, and formula of unknown Co complex by ion exchange chromatography and Fajan's method
Tutorials/exercises - 5 pages - Physics
The objective of this lab is to determine the formula of an unknown Co (III) complex through determination of outer sphere chloride content and hence total chloride content in the complex. Co (III) tends to form numerous coordination complexes, of which the most common ones are those with ammine...
The UV-vis spectra of conjugated dyes are interpreted using the multielectron particle-in-a-box model
Tutorials/exercises - 8 pages - Physics
The purpose of this lab is to observe how a real system may be approximated using the simple quantum mechanical model of a one-dimensional particle-in-a-box. Due to the arrangement of the electrons in the conjugated dyes, some electrons are free to move along the molecule's carbon-carbon...
Synthesis and analysis of ammonium vanadates and determination of water and vanadium content in ammonium decavanadate using manganometry
Tutorials/exercises - 8 pages - Physics
The objective of this experiment is to synthesize ammonium decavanadate (NH4)6V10O28.6H2O and ammonium trivanadate NH4V3O8 and subsequently determine the water and vanadium content in ammonium decavanadate. Vanadium in the +5 oxidation state forms numerous species in aqueous solution and a tight...
Determining enthalpies of reaction by calorimetry
Tutorials/exercises - 9 pages - Physics
The purpose of this lab is to determine the specific heat of the calorimeter, the enthalpy changes of 4 different reactions, namely Heat of Solution of NaOH(s), Heat of Solution of KNO3(s), the Heat of Neutralization of HCl(aq) and NaOH(aq), and the Heat of Reaction of NaOH(s) and HCl(aq), and...
Compact heat exchangers
Tutorials/exercises - 5 pages - Physics
A heat exchanger that has a large surface area per unit volume is called a compact heat exchanger. The ratio of the heat transfer surface area to that of a heat exchanger to its volume is called area density ‘?'. A heat exchanger with ?>700m2/m3 is classified as being compact. Compact heat...

Tutorials/exercises - 26 pages - Physics
Recent developments in semiconductor research technology over that last decade have lead to a renew interest in the growth of single crystals with better physical perfection and high crystal growth is newly emerging field in this study of material science which involves control phase change the...
Ion selective electrode potentiometry
Tutorials/exercises - 11 pages - Physics
The use of ISEP offers great selectivity in the determination of trace elements. With the utilization of a fluoride ion selective electrode, the concentration within the unknown sample were determined to be approximately 0.0423 +/- 3.5x10-4 mol/L. (Standard deviation = 4.58 x 10-4) In comparison...
Study of DC drives
Tutorials/exercises - 50 pages - Physics
In general practice in industrial applications machine tools make use of motors for their feed applications where in, speed of this motors are controlled in conventional methods i.e., Ward-Leonard system, multiple voltage control, rheostatic control method etc. However, these methods are...
Computer simulation study of ionic and non ionic hydration - publié le 12/01/2009
Tutorials/exercises - 6 pages - Physics
Liquids, solution, and liquid crystals present local, but not long-range order. On one hand particles in liquids interacts much strongly than the particles in gas, and this prevents the use of the usual statistical mechanics methods to predict their structure and properties since the needed...
