Abstract

From the dawn of civilization water and man are related to each other. Man lives on water but, unfortunately, cares little for it. Time has come to understand the importance of water on the earth and stop indiscriminate use of the same. Conservation of water is the need of the hour. Human Development Index and use of water are inter-related. India has different rates of precipitation in different parts of it. For example, Rajasthan with 8% of the country's population has only 1% of the total water resources of the country whereas Bihar with 10% of the country's population has 5% of water resources. A large amount of area in this country is affected by drought. The role of major dams has also been discussed.

Keywords

Water Resource, Economy, Utilization, Scarcity.

Abstract

The erosion of the river bank is a complex mechanism and sediment particles are subjected to a number of forces. Among those forces, force of cohesion between the particles plays a very significant role, and, until now, not much progress has been made to analyze the cohesive force in a comprehensive manner. It is imperative that a particle is surrounded by a family of similar sort of particles and ail are bounded together under this force of cohesion. In this article, a review of the already existing equations available for determination of the escape velocity of a particle on the riverbank is made and a new equation has been suggested. The proposed equation takes into account the micro-level variations in the system comprising of a host of particles in dynamic equilibrium.

Keywords

River Bank, Erosion, Particle Shape, Escape Velocity.

Abstract

The selection of cooling tower is influenced by a number of factors. Proper selection of cooling tower can bring the best performance out of it. A faulty selection may prove to be detrimental to the plant. The present article deals with a thorough literature survey regarding the comparative study and, therefore, the selection of cooling towers. The performance of a cooling tower is highly case-dependent and one has to be very careful a while choosing the best cooling tower for given industrial application.

Abstract

For the sixth year "Reason" is seeing the light of the day. Through all these years many a technical article has been published in "Reason" that has drawn accolades from all corners. It has always been the hallmark of the technical magazine of the college. Every year it brings in new ideas. Facts, when combined with ideas constitute the greatest force in the world. The world of science and technology always comes up with changes, and "Reason" plays its small but invaluable part in acquainting us with the changes. Somebody has rightly said, "we must dare to think 'unthinkable' thoughts.

Abstract

It is a matter of pride and pleasure that Reason is going to see the light of the day for the seventh consecutive year. Through all these years it has always been the mirror of the academic environment of Kalyani Government Engineering College in true sense. It is the beloved child of the family of the college. There has never been dearth of articles enriched with knowledge and depth. Science and technology have progressed in the last few years by leaps and bounds, and the world experiences newer dimensions in life styles, and, ironically, more and more complicated problems to face.

Abstract

The commonly used materials used for industrial piping are ferrous metallic pipes, non-ferrous metallic pipes, lined pipes&non-metallic pipes. In this articles we shall discuss about these different materials and their applications because, after all, material selection plays a major role in powerplant and process piping.

Abstract

The present work investigates turbulent supercritical (Froude Number>1) bend flow through an open channel. The CFD-based model, ANSYS FLUENT version 13.0, is used to solve the threedimensional (3D) continuity and Navier-Stokes equations. The standard k =ε turbulence model is considered for the investigation. The model is applied to the channel bend geometry as described in a published experimental work. Results in the form of velocity profiles and non-dimensional water depths are obtained and compared with the already published experimental findings. The results obtained through the present work as compared to the published ones indicate that three-dimensional modelling technique plays a significant role in the entire endeavour and, thus, the three-dimensional approach makes highly-improved predictions. Also, the three-dimensional simulation indicates the existence of a nonlinear gradient of water depth as the water flows through the bend.

Keywords

Supercritical Flow, Froude Number, Channel Bend, Turbulence.
