Principle of operation of the polarimeter: Polarimetry determines the rotation of polarized light as it travels through an optically active sample solution. A polarimeter includes a polarized light source, a filter, a sample cell, an analyzer, and a detector to measure the angle of rotation. The rotation determined can be used to measure the ...

The relays whose operation is governed by the ratio of the applied voltage to current in the protected circuit is known as impedance relay. It is a distance relay that measures the distance by equating the fault current with voltage (which equates to impedance) across the fault loop and thus trips only for the faults on the line within the …

Hydrocyclone Working Principle. The centre of this spiral is called the VORTEX. The purpose of the apex is to cause internal pressure for the cyclone and to create a vortex that extends all of the way to the top of the cyclone. In all hydrocyclones there are two outlets, one for the coarse material, this is the APEX, and the other for the …

With formal research, co-ops can help spread the educational material to governments and officials and inform future policies. Teaching the wider public about the history, principles and day-to-day operations of a co-op can create a stronger, more supportive local community. Overall, continual education is crucial for a cooperative to function.

purifier and system principles. The basic operating principle of the purifier. An efficient combustion in marine engines requires good quality fuel oil. The heavy oil used in engines is not of the purest form. In order to clean this dirty fuel, oil is sent through a series of purifying equipment's before it reaches the engine.

So, for an electrical system of frequency 50 Hz, this one cycle completes in 0.02 sec. AC motors work on the principle of Electromagnetic Induction. It converts the electrical energy (in alternating current form) to mechanical energy (rotation of shaft).

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.

The motor which works on the principle of electromagnetic induction is known as the induction motor. Electromagnetic induction is the phenomenon in which the electromotive force induces across the electrical conductor when it is placed in a rotating magnetic field. The stator and rotor are two essential parts of the motor.
