I. Lubricants selection and Application A.Viscosity Most important property of any lubricant is viscosity. A common mistake when selecting a grease is to confuse the grease consistency with the base oil viscosity. Because the majority of grease-lubricated applications are element bearings‚ one should consider viscosity selection for those applications. While most would not use an EP 220 gear oil for an oil-lubricated electric motor bearing‚ many people will use a grease containing that same oil

FLUID MECHANICS Fluids mechanics is a branch of mechanics that is concerned with properties of gases and liquids. Mechanics is important as all physical activities involves fluid environments‚ be it air‚ water or a combination of both. The type of fluid environment we experience impacts on performance. Flotation The ability to maintain a stationary on the surface of the water- varies from he on person to another. Our body floats on water when forces created by its weight are matched equally

Capricorn Anderson‚ from the book Schooled by Gordon Korman‚ and Buck‚ from The Call of the Wild by Jack London‚ were both forced into new environments without a choice and were forced to adapt. How did Buck and Capricorn successfully adapt to the new lifestyle and new environments. How did they change as characters as the story went on. When Buck and Cap were forced into leaving their original

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

Fluid Report 2 In the derivation of Bernoulli’s equation‚ the assumption of the inviscid and incompressible flow is used. However in the real case‚ the viscosity cannot be neglect and the density of the flow is not always constant. Thus Bernoulli’s equation is not always correct. For the lab‚ it is reasonable to assume the flow is inviscid and incompressible. Firstly‚ the pitot was placed at the center of the flow. The skin friction (effect of viscosity) is inversely proportional to distance

Philip Anderson spent most of his career in the brokerage business. He has worked 21 years at Stuart & Co as manager. According to him‚ in the brokerage industry‚ advisors need to provide unbiased financial advice but he realised that it was for the most part wrong. Indeed‚ company’s benefits are sometimes more important than satisfying clients expectations. The vision of being a broker in Stuart & Co appeared to be closer to the vision of Philip Anderson. Effectively‚ Stuart & Co “was a firm that

Abstract (Anderson‚ Anderson & Glanze‚ 2009) Defines evidence based practice as the practice of nursing in which the nurse makes clinical decisions on the basis of the best available current research evidence‚ his or her own clinical expertise‚ and the needs and preferences of the patient. Evidence based practice provides nurses with a method to use critically appraised and scientifically proven evidence for delivering quality health care to their patients. Research is a useful and valuable

Drunk driving “Please blow into this machine. Thank you.” If you are a driver‚ this sentence is familiar to you. Many police examine drunk driving at the crossroads every day. Meanwhile‚ numbers of advertisements and messages on TVs and radios persuade us not to drive after drinking. Driving without drinking has become a common understanding. But why do we have to accept this? And what would we do if somebody is drunk driving? Today‚ I hope to convince you that drunk driving is terrible and that
