it gives guidance on the classification of regions around equipment handling or storing flammable fluids, and provides a basis for both the correct selection of fixed electrical equipment and the location of other fixed sources of ignition in those areas. this new (4th) edition has been significantly updated from the 3rd edition to include:
different types. based on the fuel type, it is classified as liquid-fuel ramjet (fig. 3.1) and solid-fuel ramjet, fig. 3.7. and, based on the type of combustion, it can be the subsonic-combustion ramjet or the supersonic-combustion ramjet or scramjet. the previously discussed ramjets (figs. 3.1
b. types of solutions • both solvents and solutes can be solids, liquids or gases • you can have various combinations of solute and solvent phases eg) liquid in liquid – ethylene glycol (antifreeze) solid in liquid – kool aid gas in liquid – carbonated beverages solid in solid – alloys liquid in solid – mercury amalgam fillings
classification of matter matter stuff of which all materials are made: anything that has mass and takes up space. define atoms- extremely small building blocks of matter all matter is composed of atoms atoms cannot be broken down into smaller pieces by chemical means the smallest distinct units in a sample of matter elements are made up the same atoms.
geochemical classification of elements • siderophile (preferentially occur with native iron and are concentrated in earth’s core) • chalcophile ( are concentrated in sulphides) • lithophile (occur in or with silicates) • atmophile (prominent in air and other natural gas) v.m. goldschmidt.
classification of turbomachines axial-flow machines: the fluid maintains a significant axial-flow direction component from the inlet to outlet of the rotor. mixed-flow machines: there may be significant radial-and axial-flow velocity components for the flow through the rotor row. radial-flow mahcines: the flow across the blads involves
traditionally the three major classes of materials are metals, polymers, and ceramics. examples of these are steel, cloth, and pottery. these classes usually have quite different sources, characteristics, and applications. chemists have learned that the macroscopic (visible) properties of matter are related to its
the study of fluid flow or the study of flowing fluids can be called hydrodynamics, as we called the study of stationary or static fluid hydrostatics. in hydrodynamics we analyze, track, and predict the variations of flow parameters with space and time. in this article we will study classification of fluid flow in different types according to the conditional variations of the flow parameters
2. nuclear energy. in the classification of resources, nuclear energy is classified as non-renewable. the fuel used for nuclear energy is generally uranium, which is in a limited supply. so we classify it as non-renewable. production of electricity from nuclear energy does not release carbon dioxide. thus, use of nuclear energy is safe for the
aromatic oils are used for manufacturing seal compounds, adhesives and as plasiticezers in rubber and asphalt production. semi-fluid lubricants (greases) semi-fluid lubricants (greases) are produced by emulsifying oils or fats with metallic soap and water at 400-600°f (204-316°c). typical mineral oil base grease is vaseline.
according to bohr’s theory, every shell of an atom contains a discrete amount of energy at different levels. energy band theory explains the interaction of electrons between the outermost shell and the innermost shell. based on the energy band theory, there are three different energy bands: valence band; forbidden energy gap; conduction band
classification according to flow arrangements single-pass multipass counter flow parallel flow cross flow split flow divided flow extended surface cross-counter flow cross-parallel flow compound flow shell-and-tube plate parallel counter flow m-shell passes n-tube passes split-flow divided-flow fluid 1 m passes fluid 2 n passes
there are five slope classifications: · adverse (a) if so < 0 (slope is positive in the downstream direction) · horizontal (h) if so = 0 · critical (c) if yo = y c · mild (m) if so> 0 and y n > y c ·
centrifugal pump classification by flow. centrifugal pumps can be classified based on the manner in which fluid flows through the pump. the manner in which fluid flows through the pump is determined by the design of the pump casing and the impeller. the three types of flow through a centrifugal pump are radial flow, axial flow, and mixed flow.
matter can be classified into two basic categories. matter is either a mixture or it is a pure substance. we can classify mixtures into two categories - homo...
the classification of petroleum. for several decades now the crude oil or petroleum industry has classified the raw crude by the location from which it was extracted. in other words, oil is classified by geographic region. however, all oils from a particular region are not created equal. further classification of petroleum, derived from the
classifications: metals, ceramics, and polymers. this scheme is based primarily on chemical makeup and atomic structure, and most materials fall into one distinct grouping or another, although there are some intermediates. in addition, there are the composites, combinations of two or more of the above three basic material classes.
today, more than one thousand prototypes of wave energy converters (wecs) exist, and there are several classification schemes based on their characteristics. [4-6] in particular, the wecs can be categorized by converter types and energy conversion principles, based on a pressure differential, mechanical flexing and bobbing, overtopping, and hydraulic flapping.
an automobile is a vehicle that is capable of propelling itself. since the 17 th century, several attempts have been made to design and construct a practically operative automobile.. today, automobiles play a crucial role in the social, economic and industrial growth of any country. after the designing of internal combustion engines, the automobile industries has seen a tremendous growth.
2. liquids can change their shape (flow); solids can’t. gases can undergo large volume changes as pressure changes; liquids do not. gases flow and change volume; solids do not. 4. the mixture can have a variety of compositions; a pure substance has a definite composition. both have the same composition from point to point. 6.
includes 2 classifications: the 20(s)-protopanaxadiol (ppd) and 20(s)-protopanaxatriol (ppt) classifications. p. notoginseng contains high levels of rb1, rd (ppd classification) and rg1 (ppt classification)ginsenosides. rb1, rd and rg1 content of p. notoginseng is found to be higher than that of p. ginseng and p. quinquefolius in one study.
• internal energy, u: the sum of all the microscopic forms of energy. the macroscopic energy of an object changes with velocity and elevation. • kinetic energy, ke: the energy that a system possesses as a result of its motion relative to some reference frame. • potential energy, pe: the energy that a system possesses as a result
conservation of energy (first law of thermodynamics) in this course we’ll consider the motion of single phase fluids, i.e. either liquid or gas, and we'll treat them as continuum. the three primary unknowns that can be obtained by solving these equations
2) fluid density is constant dv 3) flow is steady: =0 (no time dependence or turbulence) dt 4) fluid is “inviscid” or can be approximated as inviscid. no frictional effects 5) no work added! we can derive this through a lagrangian derivation: looking at a small elemental volume along a streamline d∀=dn ds dx (dx is the depth into the paper).

load (called output source). however, in the case of a change of direction of the energy flow, i.e., a change in the sign of the power, the sources (generat ors and loads) can exchange their functions (i.e., restitution of energy of a magnet towards the grid). 2.1 nature of sources 2.1.1 definitions
