Drag Reduction Annular Flow with Poly Acryl Amide Additive
Abstract: Drag reduction studies have been showed in annular flow with polyacrylamide additive. The percentage drag reduction in annular pipe flow ranges between 85–98% as the diameter increased from 0.02 to 0.033 m. The percentage drag decrease of 89 to 98% is detected as the polyacrylamide concentration is varied from 50 to 200 ppm. The correlation for drag reduction and Reynolds number is presented here under DR = 2.06Re-0.037. Keywords: Drag …

Spectrophtometric Study of Catalysed Oxidation of Some Cyclic Alcohols by N-bromophthalimide
Abstract: The spectrophotometric kinetic investigation of cyclohexanol and cycloheptanol catalysed by Keggin type anion [PW12O40]3- with N-bromophthalimide have been carried out in 30% acetic acid medium in absence of mercuric(II) acetate and in presence of sulphuric acid. The observed kinetic data was used for the justification of Beer-Lambert law. The reactions follow a fractional-order with respect to cyclic alcohols, PTA catalyst and first-order with respect to oxidant NBP. The added H+ …

Determination of the Flow Velocity Resistance in Non- Submerged Woody Plants
Abstract: Vegetation on the bank of a river or stream has a major influence on resistance, velocity distribution,and turbulence force. The resistance to flow in open channels depends on different channel and flow parameters. Out of many factors, vegetation is the mainly important parameter in open channels. In this study have been five points to measure the velocity in the channel. The experimental work has been done by a rectangular channel …

Different type of catalysts used in the Baylis-Hillman reaction
Abstract: The Baylis-Hillman reaction in the present-day version is an atom-economic carbon-carbon bond-forming reaction between the α-position of the activated alkenes and carbon electrophiles under the influence of a catalyst or catalytic system offering diverse classes of densely functionalized molecules. If the substrate contains both the activated alkene and electrophile components in appropriate positions, there is the possibility of developing an intramolecular version of this reaction leading to the synthesis of …
