Heat transfer through a fluid medium is important in several engineering applications and is largely convection dominated. However, the convective heat transfer coefficient is strongly dependent on the thermal conductivity of fluid. A nanofluid is a stable colloidal suspension of a low volume fraction of ultrafine solid particles of nanometric-dimension dispersed in conventional heat transfer fluid. In this study the heat transfer parameters like convective heat transfer coefficient and Nusselt number are studied for CuO-water nanofluid samples of different volumetric concentration. These tests are to be compared with the benchmark water-water heat transfer experiment, to look for possible enhancement.

Sustainable power source assumes a key job in the progress toward a low carbon economy and the arrangement of a protected supply of vitality. Geothermal vitality is an adaptable source as a type of manageable power source that satisfies the standard need. since some geothermal power plants, (GPPS) faces various frustrations the essential of a technique for gathering planning to abstain from or decrease potential disillusionments is huge. Since no specific conveyed record of considering a FMEA associated with packs with essential disillusionment mode shave been found starting at now in this paper the utilization of dissatisfaction modes and effects assessment FMEA as an invaluable technique for choosing to describe and separating normal frustrations in an ordinary application is considered. Consequently a legitimate peril scoring of occasion area and earnestness of frustration modes and figuring the danger need number RPN for recognizing high potential disillusionments is cultivated. To help exactness and ability to research the method approval writing computer programs are utilized.

Globalization, advanced technology, and increasingly sophisticated customer demands change the way of conducting business. Old business models not extensive work in the new economy. The defects rate of the product plays an essential role in the enhancement of yield and financial situations of any firm. The objective of this paper is to study and evaluate current processes of the eye bolt manufacturing organization, to find out the current process sigma level and to improve existing sigma level through productivity improvement. According to the customer needs or requirements, the current sigma level of the Eyebolt manufacturing process has been calculated, and suggestions are provided for improvement. This has been done by using Six Sigma DMAIC methodology.

Lean Six Sigma is a methodology in a network arranged joint effort to improve the show by productively ousting waste and diminishing assortment. It joins lean collecting and Six Sigma to get rid of the waste. In a collecting association, it is major to improve the methodology. In this examination, Lean Six Sigma gadgets are used to the Strainer fragment creating industry to dismember and improve the collecting system. It is seen that the strainer part amassing is out of detail most remote point and age was unreliable. The primary driver of frustration is recognized, poor down and by using Lean six sigma devices improvement is made.

The technology has developed more in the field of agriculture by using different developed tools like machines and robots for doing different works, but nowadays there is no land for cultivation due to destruction of agriculture lands and cost of these equipment’s is high for the farmers in our country. The aim is to develop the small-scale low-cost agriculture robot for farmers to make house farming. This developed robot overcomes these issues, it is a multifunctional robot which can do different operations like seeding, ploughing, watering, weeding etc. which is controlled by the microcontroller, and this robot is user friendly for the farmers. By giving inputs like length, breadth and crop varieties in the program the robot can perform certain operation automatically. This robot helps the users to cultivate the crops in the home with optimum usage of space without using lands.
