quantity of work definition

The various forms of biomass are mixed with an equal quantity of water in the mixing tank. This forms the slurry. The slurry is fed into the digester through the inlet chamber. When the digester is partially filled with the slurry, the introduction of slurry is stopped and the pla..

The various forms of biomass are mixed with an equal quantity of water in the mixing tank. This forms the slurry The slurry is fed into the digester through the inlet chamber. The temperature of the slurry must be maintained around 35 o C. Any drop in temperature will reduce the ana..

Slurry (mixture of equal quantities of biomass and water) is prepared in the mixing tank. The prepared slurry is fed into the inlet chamber of the digester through the inlet pipe. The plant is left unused for about two months and introduction of more slurry is stopped. During t..

Work and Measurement of Work - Let us now discuss the conditions to be satisfied for work to be done. From the above examples, it is clear that work is said to be done when a force acts on an object and the point of application of the force moves in the direc..

Work is said to be done when a force acts on an object and the point of application of the force moves in the direction of force. Conditions to be satisfied for work to be done: Some force must act on the object The point of application of force must move in the direction of for..

In 1798, Count Rumford observed that the amount of heat produced is proportional to the amount of mechanical work done. Later, Dr. James Prescott Joule of Manchester, established a definite relation between the work done and the heat produced. It was shown that when a ..

If we rub our hands for a while, the hands become warm. Let us examine the process. Rubbing hands is mechanical work and in this process heat is generated. We can say heat energy is produced as a result of mechanical work. Let us examine another example - when you light a matchs..

For a layman the term 'work' implies any activity resulting in muscular or mental exertion. In physics, however, the term has a different meaning. It represents a physical quantity..

Work Energy Theorem - According to this principle, work done by a force in displacing a body, gives the measure of the change in kinetic energy of the body. When a force does some work on a body, the kinetic energy of the body increases by the same amount. Conversely, ..
