Improving the power factor of a circuit

Presentation - 51 pages - Physics

The power factor of a circuit implies that how efficiently power is being consumed or utilized in the circuit. The greater the power factor of a circuit, greater is the ability of the circuit to utilize apparent power. Thus if the power factor is 0.5, it means that 50% of the power is being...

A presentation on the hydrodynamic modeling of circulating fluidized bed

Presentation - 42 pages - Physics

Fluidization is an operation through which fine granular solids are transformed into a fluid like state through contact with a gas or liquid. An increase in the gas velocity through a granular solid brings about changes in the mode of gas solid contact in many ways. Among the several flow regimes...

Co-generation (18 slides)

Presentation - 5 pages - Physics

In this presentation you will learn a bit about Co-generation. It is the concept of producing two forms of energy from one fuel. Co-generation (also combined heat and power or CHP) is the use of a heat engine or a power station to simultaneously generate both electricity and useful heat. It is a...

Applications of aqueous equilibria

Presentation - 90 pages - Physics

When AgNO3 is added to a saturated solution of AgCl, it is often described as a source of a common ion, the Ag+ ion. By definition, a common ion is an ion that enters the solution from two different sources. Solutions to which both NaCl and AgCl have been added also contain a common ion; in this...

Equilibrium: Heat energy

Presentation - 90 pages - Physics

Heat is energy flowing from a high temperature object to a low temperature object. When the two objects are at the same temperature, there is no net flow of energy or heat. That is why a covered cup of coffee will not be colder than or warmer than the room temperature after it has been in there...

Generating Electricity

Presentation - 10 pages - Physics

The blade of a turbine is tilted an angle. Movement of the air is channeled creating low and high pressures on the blade that force it to move. The blade is connected to a shaft which in turn is connected to an electrical generator. The mechanical energy of the turning blades is...
