Water and land are limited natural resources to be distributed among all equitably. Rainfall is the main source of runoff. The accurate estimate of available water resource is required to meet the raising demand for water from different sectors.. Morphometric parameters and runoff estimation helps in appropriate planning for, optimum utilisation of water, conservation, recharging of the ground water zones, reducing the soil erosion and management of floods. The study area chosen is Kabini Command area spreads in Mysore and Chamarajnagara districts. It is located between 760 12’ 0 ’’ E and 770 12’ 0 ’’ E longitude and 110 58’ 0 ’’ N and 120 16’ 0 ’’ N with an area of 5985.48 km2 and is covered in Survey of India (SOI) Toposheet number 57H04, 57H03, 57D16, 58E01, 58A13, 57D12, 57D08, 58A05 and 58A01 on 1:50000 scale. Remote sensing and GIS techniques are used to delineate the entire catchment into 7 watersheds. Morphometric analysis is carried out at the watershed level to understand the hydrological process and to derive the inferences from the watershed parameters. The bifurcation ratio ranges between 4 to 5 which shows the geological structure do not distort drainage pattern. The drainage density varies from 1.49 to 2.65 km/km2 indicating the area is coarse and moderate in texture. Watershed is more elongated as the elongation ratio ranges from 0.34 to 0.42. Hypsometric analysis is done for the catchment to reveal the stages of geomorphic development. Hypsometric integral quantifies the geological stages of development and erosion proness of Kabini command area. Hypsometric integral has estimated by graphical plot of measured contour elevation and encompassed area by using empirical formulae

A single layer dual-polarized.microstrip patch antenna with dual port is designed, simulated and analyzed. The two ports are provided with a phase shift and designed to operate in the C-band with a solution frequency at 4GHz. The edges of the patch are etched which helps to improve the polarization of the designed antenna. The inset feed is the feeding technique used for the design of the dual-polarized antenna which provides a gain of about 8.5dB. This paper describes the parameters of the dual-polarized patch antenna like VSWR, Radiation Pattern, Axial Ratio and Return Loss are simulated and results are recorded. The proposed antenna works for the single narrow band frequency having a return loss lesser than -10dB and finds its application in satellite communications and weather RADAR.

Energy Deficiency can be reduce by use of waste and available forms of energy (Non-conventional) to produce electricity or utilize them to reduce usage of other power absorbing devices as the world is facing energy crisis and as our fuel resources are depleting very fast. In Conventional Power Producing methods wasted heat can be recovered in Boiler accessories like Economizers and Air Preheaters with less effectiveness. Current work is investigation of various aspects of convective heat transfer enhancement using Pin Fins, Corrugated Tubes and Twisted Tapes. The basic methods used to enhance the heat transfer by simultaneous increase of heat transfer surface area as well as the heat transfer coefficient. The method is carried out as on combination of Pin Fins, Corrugated Tubes and Twisted Tape as elements for the heat transfer enhancement, Investigations of a double-pipe Pin Fin heat exchanger were carried out. The heat transfer and pressure drop results for the Pin Fin and Corrugated tube heat exchanger were compared with the results for a smooth-pipe heat exchanger. It was found that by a direct comparison of Nusselt number Nu and Euler number Eu, conclusion regarding the relative performances could be made. Geometric parameters are considered, Ratio of Spacing between the fins and diameter of Pin Fin and the Ratio of Corrugated Tube diameter and diameter of corrugation. Heat transfer depends on numbers of Pins and spacing between pins. In this study Heat transfer enhancement is found to be about 5-15% for Pin Fin and 6-23% for Corrugated Tube with Twisted Tape. This Improvement will effectively improvise the overall efficiency of Conventional and Non-Conventional Power Plants
