Thermodynamics Periods 18 Concepts of system, types of systems, surroundings, work, heat, energy, extensive and intensive properties, state functions. Throttle lag occurs because turbochargers rely on the buildup of exhaust gas pressure to drive the turbine. Electrical boosting "E-boosting" is a new technology under development.

Some technologies at the cutting edge of mechanical engineering are listed below see also exploratory engineering.

CBSE, Class XI Chemistry

Mole concept and molar mass; percentage composition and empirical and molecular formula; chemical reactions, stoichiometry and calculations based on stoichiometry.

Project Periods 10 Scientific investigations involving laboratory testing and collecting information from other sources. Throttle lag occurs because turbochargers rely on the buildup of exhaust gas pressure to drive the turbine.

Environmental Chemistry Periods 6 Environmental pollution — Air, water and soil pollution, chemical reactions in atmosphere, smogs, major atmospheric pollutants; acid rain, ozone and its reactions, effects of depletion of ozone layer, greenhouse effect and global warming — pollution due to industrial wastes; green chemistry as an alternative tool for reducing pollution, strategy for control of environmental pollution.

Unsourced material may be challenged and removed. Unit IX Hydrogen Periods 8 Position of hydrogen in periodic table, occurrence, isotopes, preparation, properties and uses of hydrogen; hydrides — ionic, covalent and interstitial; physical and chemical properties of water, heavy water; hydrogen peroxide-preparation, reactions, use and structure; hydrogen as a fuel.

CBSE Class XI Chemistry

When he removed his front cylinder, there was NO piston. Determination of pH of some solutions obtained from fruit juices, solutions of known and varied concentrations of acids, bases and salts using pH paper or universal indicator. Robots are used extensively in industrial engineering.

Chemical Bonding and Molecular Structure Periods 16 Valence electrons, ionic bond, covalent bond, bond parameters, Lewis structure, polar character of covalent bond, covalent character of ionic bond, valence bond theory, resonance, geometry of covalent molecules, VSEPR theory, concept of hybridization involving s, p and d orbitals and shapes of some simple molecules, molecular orbital theory of homonuclear diatomic molecules qualitative idea only.

The car would not run correctly for very long although the piston event is gone air would seep in via the crank case pressure and the gas would still fire in.

That was his last run of the week, so he packed up the bike and went home.

Questions and Answers

Atomic and molecular masses. Micro electro-mechanical systems MEMS [ edit ] Micron-scale mechanical components such as springs, gears, fluidic and heat transfer devices are fabricated from a variety of substrate materials such as silicon, glass and polymers like SU8.

Generally, a turbo-normalized system attempts to maintain a manifold pressure of This limits boost at a particular RPM, regardless of exhaust gas pressure. Important compounds of silicon and a few uses: I know this has nothing to do with the basis of the thread, I just thought it was an interesting true story.

Optionally, an engineer may also manually manufacture a part using the technical drawings.


Ina similar system that used a hydraulic drive system and overspeed clutch arrangement accelerated the turbocharger of the MV Canadian Pioneer Doxford 76J4CR engine. Reducing the "boost threshold rpm" can improve throttle response. Carbon - catenation, allotropic forms, physical and chemical properties; uses of some important compounds: The one who studies Outside the factory, robots have been employed in bomb disposal, space explorationand many other fields.

This is representative of the extra air pressure that is achieved over what would be achieved without the forced induction. Twin-scroll[ edit ] Twin-scroll or divided turbochargers have two exhaust gas inlets and two nozzles, a smaller sharper angled one for quick response and a larger less angled one for peak performance.

The turbocharger's compressor draws in ambient air and compresses it before it enters into the intake manifold at increased pressure. This is due to the time needed for the exhaust system and turbocharger to generate the required boost which can also be referred to as spooling.

Thermodynamics principles are used by mechanical engineers in the fields of heat transferthermofluidsand energy conversion. This lets the balance between performance, response, and efficiency be tailored to the application.

Crystallization involving impure sample of any one of the following: The amount of air actually inspired, compared with the theoretical amount if the engine could maintain atmospheric pressure, is called volumetric efficiency.

When he removed his front cylinder, there was NO piston. Homolytic and heterolytic fission of a covalent bond: Students have to go through a lot in order to complete their education with top ranking.

Third law of thermodynamics —Brief introduction. Twin-turbo Twin-turbo or bi-turbo designs have two separate turbochargers operating in either a sequence or in parallel. Newer turbocharger and engine developments have steadily reduced boost thresholds.

Consider the combustion of methane as an example:. We’d love to answer them for you, or have you answer them for us! Post your questions in the comments form below and the douglasishere.com staff will try to answer them for you.

Essay on Comparing the Enthalpy Changes of Combustion of Different Alcohols - Comparing the enthalpy changes of combustion of different alcohols Planning What are alcohols.

===== Alcohol is the common family name for the hydrocarbon group alkanols. Mechanical engineering is the discipline that applies engineering, physics, engineering mathematics, and materials science principles to design, analyze, manufacture, and maintain mechanical douglasishere.com is one of the oldest and broadest of the engineering disciplines.

The mechanical engineering field requires an understanding of core areas including mechanics, dynamics, thermodynamics. is and in to a was not you i of it the be he his but for are this that by on at they with which she or from had we will have an what been one if would who has her.
