For each problem (momentum‚ energy & mass)‚ we will start with an initial chapter dealing with some results of the molecular theory of the transport phenomena (viscosity‚ thermal conductivity & diffusivity) Then‚ proceed to microscopic level and learn how to determine the velocity‚ temperature and concentration profiles in various kinds of systems. Then‚ the equations developed at microscopic level are needed in order to provide some input into problem solving at macroscopic

characteristics of clays? Clay is an inorganic materials mineral which contain on fine particle‚ normally grain size is near about <1/256mm. It shows good plasticity in wet form but become brittle when it is dried. It is good insulter of electricity and thermal conductivity. Porosity is also another important characteristic of clay.[1‚ 2] (b)What is the structure of clays? Mostly‚ clays have layers structure. They form combination of tetrahedral silicates and octahedral aluminates. But there is also chain structure

gravity depends on the Earth being present‚ we say that the "Earth-book system" is what really possesses this potential energy‚ and that this energy is converted into kinetic energy as the book falls. Thermal‚ or heat energy: Consider a hot cup of coffee. The coffee is said to possess "thermal energy"‚ or "heat energy" which is really the collective‚ microscopic‚ kinetic and potential energy of the molecules in the coffee (the molecules have kinetic energy because they are moving and vibrating

Advantages of AAC Blocks shaped by the aac autoclave ASME AAC Autoclave is the pressure vessel and key equipment in the production of aerated concrete and autoclaved brick. It is applicable for curing the cut body or brick under high temperature and high pressure. The working medium is saturated water vapor. The main parts are made by autoclave body‚ cover‚ hand-operated reducer‚ safe blocking device‚ support saddle‚ valve meter etc. The body is a principle and cylindrical device made of steel

Unit 4: Carbon Nanostructures Carbon Structures: • Carbon contains six electrons with electronic structure: (1s2)‚ (2s)‚ (2px)‚ (2py)‚ (2pz). Outer s orbital together with three p orbitals form the chemical bonds of carbon with other atoms. • Conventionally‚ solid carbon has two main structures called allotropic forms: diamond and graphite: - Diamond is tetrahedrally bonded through sp3 hybrid bonds that form a 3D network. - Graphite has a layered structure with each layer called graphene formed
