Unit 004: Understand how to apply scientific principles within mechanical services engineering Glossary of terms Term Explanation Alloy A metal made up of a combination of two or more materials. Atmospheric pressure The weight of air creates a pressure on the Earth’s surface and the pressure exerted by the weight of air pressing down on the ground below will vary depending on the ground’s height above sea level. Boiling When a liquid vaporises. Capillary action When water is drawn

factors like altitude and air density. The speeds in ideal gases and air have their own formulas: Thus‚ For a gas the K is given by the formula above‚ and the C is the coefficient of stiffness in solids. Thus the second formula is given. (Gamma) is the adiabatic index‚ then is the pressure‚ and the regular P is the density. In general‚ the speed of sound is given in the formula: K is a coefficient of stiffness‚ the bulk modulus‚ and P is the density. Then there is a more complex

quantity of suspended particles and produce a clear effluent. Classification of Settleable Solids There are different factors to be consider in choosing the type of sedimentation to be used‚ some of it are particle size‚ viscosity‚ solid and solution densities as well as the characteristics of the particles within the slurry. In this figure‚ it illustrates the relationship between solid concentration‚ interparticle cohesiveness and the type of sedimentation that may exist. Totally discrete

and accurately than measurements of volume. Therefore‚ the mass of the liquid contained or dispensed by the glassware will be measured and the corresponding volume calculated using the density of the liquid. However‚ a relatively small change in temperature causes a change in the liquid’s volume and thus its density. 1.2 To Contain vs To Deliver Volumetric glassware is calibrated either to contain (TC) or to deliver (TD) the stated volume. Beakers and graduated cylinders are generally calibrated

Severe Notes 4/25/13 When ML AND UL flow reach an updraft and that midlevel and upper level flow tends to be subsaturated‚ so there are 3 options with this upward rotating flow can go left right or down. Can’t go up because air tends to be denser then the updraft air. So if that air goes down it gains downward momentum. Bc that air gains downward momentum which will evap cool it will continue to gain neg buoyancy. Once at the surface you have your RFD. Large precip surrounding the updraft which

Ralph - One of the main characters in the novel. He has many characteristics such as being very athletic‚ charismatic‚ leading‚ and a smart protagonist of the group of kids. Ralph was elected the leader of the boys at the beginning of the book. While most of the other boys are mainly concerned with having fun and not doing any work‚ Ralph focuses on building huts and thinking of ways to increase their chances of being rescued. Ralph’s influence over the other boys is safe at the beginning of the
