Band broadening theory (Van Deemter equation) It is well recognized now that column band broadening originates from three main sources: 1. multiple path of an analyte through the column packing; 2. molecular diffusion; 3. effect of mass transfer between phases. In 1956 J.J. Van Deemter introduced the equation which combined all three sources and represented them as the dependence of the theoretical plate height (HETP) on the mobile phase linear velocity. Originally‚ it was introduced for gas

Heat Equation from Partial Differential Equations An Introduction (Strauss) These notes were written based on a number of courses I taught over the years in the U.S.‚ Greece and the U.K. They form the core material for an undergraduate course on Markov chains in discrete time. There are‚ of course‚ dozens of good books on the topic. The only new thing here is that I give emphasis to probabilistic methods as soon as possible. Also‚ I introduce stationarity before even talking about state classification

INTRODUCTION Diamond Chemicals a major global competitor in the chemical industry and a leading producer of polypropylene. In 2001 the Corporation was facing losses in earnings and the slowdown of the global economy. The Earning per Share (EPS) had fallen by 50% from 1999 to 2000. The controller of the plant in Merseyside proposed a project of £9 million to renovate and rationalize the polypropylene production line at the plant to compensate for deferred maintenance and to exploit opportunities

BERNOULLI AND ENERGY E Q U AT I O N S his chapter deals with two equations commonly used in fluid mechanics: the Bernoulli equation and the energy equation. The Bernoulli equation is concerned with the conservation of kinetic‚ potential‚ and flow energies of a fluid stream‚ and their conversion to each other in regions of flow where net viscous forces are negligible‚ and where other restrictive conditions apply. The energy equation is a statement of the conservation of energy principle and is applicable

For those of you who came to the review in class today‚ The stoichiometry question from class. I read the answer to the wrong decimal place. --What is the total mass of oxygen in 0.26mol of Cu2O? Find the percent of oxygen in Cu2O first. The molar mass of Cu2O is 143‚ the mass of just the oxygen in it is 16. % Composition of oxygen would be 16/143 times 100 is 11.19%‚ To determine the mass of Cu2O in 0.26 mol‚ multiply by the molar mass of Cu2O. This gives
