Title: Pelton wheel Objectives: 1. To familiarize with the working principle of Pelton Wheel. 2. To determine the characteristics of Pelton Wheel. 3. To determine the optimum efficiency point. Introduction: The pelton wheel is a very efficient impulse turbine invented by Lester Allan Pelton. The water jet shot the turbine blade and the forces are divided into two symmetrical parts. Unlike other turbine blade Pelton’s paddle geometry was designed so that when the rim runs at ½ the speed

RELATION BETWEEN PERSONALITY TRAITS AND COLOR PREFERENCE Introduction People of all generations and cultures have used color to express feelings and emotion. Color preferences are personal expressions for life such as using in clothes‚ shoes‚ bags‚ room painting‚ and etc. Although some of the colors are the popular for the fashion‚ people mostly chose the color which expresses themselves. Some people refrain from using color because they do not understand how to use it or hesitate not to reflect

simple Pelton wheel rig for experimental use in a university laboratory. The final design should be able to be built with the equipment and resources at the university and be able to be operated with the most basic knowledge of water turbines. This report also goes into the theory of turbines and power generation‚ particularly in larger scale water turbines that are used across the globe. Conducting experiments using this rig should provide students with basic knowledge about the Pelton wheel and the theory

For the design research I have decided to choose color theory. As defined‚ color theory is a body of practical guidance to color mixing and the visual impacts of specific color combinations. Color theory is based on more subtractive color which is usually the color that we see around on a day to day life‚ or sometimes used in painting and printing. Color has played an important role in communication‚ psychology‚ and even physical health giving color power. Whether it is in interior design‚ graphic

ASSIGNMENT 1 Case study 1 Reinventing the Wheel at the Apex Door Company Jim Delaney‚ president of the Apex door‚ has a problem. No problem how often he tells his employees how to do their jobs‚ they invariably “decide to do it their way”‚ as he puts it‚ and arguments ensue between Jim‚ the employee‚ and the employee’s supervisor. One example is the door design department‚ where the designers are expected to work with the architects to design doors that meet the specifications. While
