Introduction My research is based on how Ohm’s law is derived and how it is used to solve problems in series and parallel connection and the resistance of a material. Ohm’s Law shows the relationship between the voltage (V)‚ current (I) and resistance (R). It can be written in three ways: V = I × R or I =V/R or R = V/I The resistance (R) of a material depends on Its length‚ cross-sectional area‚ The resistivity‚ and Resistance also depends on temperature‚ usually

Centrifugal pump A centrifugal pump is a rotodynamic pump that uses a rotating impeller to increase the pressure of a fluid. Centrifugal pumps are commonly used to move liquids through a piping system. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller‚ flowing radially outward into a diffuser or volute chamber (casing)‚ from where it exits into the downstream piping system.[1][2] Centrifugal pumps are used for large discharge through smaller

CENTRIFUGAL PUMPS Introduction A centrifugal pump is a rotodynamic pump that uses a rotating impeller to create flow by the addition of energy to a fluid. Centrifugal pumps are commonly used to move liquids through piping. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller‚ flowing radially outward into a diffuser or volute chamber (casing)‚ from where it exits into the downstream piping.

Heat Pump ------------------------------------------------- A heat pump can provide an alternative to using your air conditioner. * Heat pumps can supply heat‚ cooling‚ and hot water. * Your climate and site will determine the type of heat pump most appropriate for your home. For climates with moderate heating and cooling needs‚ heat pumps offer an energy-efficient alternative to furnaces and air conditioners. Like your refrigerator‚ heat pumps use electricity to move heat from a

Heat pump From Wikipedia‚ the free encyclopedia Jump to: navigation‚ search For theoretical background‚ see Heat pump and refrigeration cycle. Outdoor components of a residential air-source heat pump A heat pump is a machine or device that transfers thermal energy from one location‚ called the "source‚" which is at a lower temperature‚ to another location called the "sink" or "heat sink"‚ which is at a higher temperature. Thus‚ heat pumps moves thermal energy opposite to the direction that

Submersible Pump Application The system consists of a submersible pump controlled by a Danfoss VLT AQUA Drive and a pressure transmitter. The transmitter gives a 4-20 mA feedback signal to the VLT AQUA Drive‚ which keeps a constant pressure by controlling the speed of the pump. To design a drive for a submersible pump application‚ there are a few important issues to take into consideration. Therefore the drive used must be chosen according to motor current. 1. The motor is a so called “Can motor”
