Q1 (a) Define density and relative density. What are the different units of measurement of density? (b) Explain how the relative density of a liquid is found using specific gravity bottle. (c) A metal casting is expected to have a specific gravity of 7.5. Due to entrap air bubbles the actual specific gravity was found to be 6.5. What percentage of the casting filled with air? (Neglect the mass of air in calculation). Q2 (a) Write down the relationship for the dynamic viscosity of fluid in terms of

Overview A transistor is a semiconductor device that amplifies and switches electrical currents. They are the core component of any modern electronic devices‚ such as computer‚ telephones and other electronics. Nowadays most transistors are use to produce integrated circuits. There were a numerous inventions‚ or problems with the inventions that lead to the birth of the transistor. Radio signals‚ could be sent carrying information over a long distance away; the only problem was there was no device

thermometer are adjusted to specific densities by the differing amounts of liquid and even the type of liquid within the glass. The different densities will be affected by the waters density‚ which changes as it expands or contracts with temperature difference. As the temperature within the room heats up‚ so does the temperature of the water within the vertical glass tube. Once the water within the thermometer is room temperature‚ the glass bubbles densities will either be more or less dense than

Aggregates for Concrete Aggregates are inert granular materials such as sand‚ gravel‚ or crushed stone that‚ along with water and cement‚ are an essential ingredient in concrete. Aggregates are the most mined materials in the world. For a good concrete mix‚ aggregates need to be clean‚ hard‚ strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the deterioration of concrete. Aggregates‚ which account for 60 to 75 percent of the total volume

INTRODUCTION Archie Unleashed is an attempt to put the basic log analysis methodology for computing water saturation into a readable reference document. The beginning log analyst or petrophysicist should have little difficulty with the terms and concepts utilized in this paper‚ however‚ most terms are redefined in appendix A. The basic outline of this document closely follows a previous work written for the casual interpeter in log analysis. Archie Unleashed is meant to carry that work one step

Solutions (Week-01) Chapter-01 1-12 A plastic tank is filled with water. The weight of the combined system is to be determined. Assumptions The density of water is constant throughout. Properties The density of water is given to be = 1000 kg/m3. Analysis The mass of the water in the tank and the total mass are mw =V =(1000 kg/m3)(0.2 m3) = 200 kg mtotal = mw + mtank = 200 + 3 = 203 kg Thus‚ 1-14 The variation of gravitational acceleration above the sea level is given as

The film happens with a great taste of honesty. It teaches lessons you can use in your daily lives. The movie starts with the Gardner couple having problems‚ which is a common scene for people nowadays. The protagonist earns money by selling bone density scanners which he sells to medical institutions‚ which does not sell much. Chris Gardner’s lack of ability to make a living made her wife Linda to leave them. It gives us the picture that people can be full of other’s crap that they will leave you
