It describes how centrifugal pumps work by converting mechanical energy to hydraulic energy using centrifugal force. They work on the principle of forced vortex flow. Key components include an impeller that rotates and accelerates the fluid outward, and a casing that captures the fluid and converts its kinetic energy to pressure. ...

2. Introduction A refrigerator (colloquially fridge) is a popular appliance that consists of a thermally insulated compartment and a heat pump (mechanical, electronic or chemical) that transfers heat from the inside of the fridge to its external environment so that the inside of the fridge is cooled to a temperature below the ambient temperature of the room. …
6. 6 • The grinding machine consists of a bed with a fixture to guide and hold the work piece, and a power-driven grinding wheel spinning at the required speed. The speed is determined by the wheel's diameter and manufacturer's rating. The user can control the grinding head to travel across a fixed work piece, or the work piece can be moved while the grind …
The document provides information about permanent magnet synchronous motors (PMSM), including their construction, working principle, advantages over induction motors, and applications.

3. Major Parts of Wind Turbine A simple wind turbine consists of three main parts, the blades, shaft and generator 1) Blades: The blade acts as barriers to the wind. When the wind forces the blade to move, some of the wind energy is transferred to the rotor. 2) Shaft: When the rotor spins, the shaft also spins, and transfers the mechanical energy into rotational energy. …

8. Nuclear (Atomic) Power Plant… Nuclear fission… U235 splits into two fragments (Ba141 & K92 ) of approximately equal size. About 2.5 neutrons are released. 1 neutron is used to sustain the chain reaction. 0.9 neutrons is absorbed by U238 and becomes Pu239 . The remaining 0.6 neutrons escapes from the reactor. The neutrons produced move at a very high …
• Principle of Operation A rotating field is set up in the stator when a 3- Phase supply is given. The stationary rotor cut the revolving field and due to electromagnetic induction an e.m.f. is induced in the rotor conductor. As the rotor conductor is short circuited current flows through them. It becomes a current carrying conductor in ...
WORKING PRINCIPLE A voltage is applied across the anode and cathode. Current flows from cathode to anode through the organic layers. Electrons flow to emissive layer from the cathode. Electrons are removed from conductive layer leaving holes. Holes jump into emissive layer . Electron and hole combine and light emitted.
8. In a three phase induction motor, the induced emf in the rotor circuit depends on the slip of the induction motor and the magnitude of the rotor current depends upon this induced emf (electromotive force). When the motor …
Thermostat working principle A thermostat is a component which senses the temperature of a system so that the system's temperature is maintained near a desired set point. Thermostats are used in any device or …

2. SPRAY DRYING Produce powders with a specific particle size and moisture content. Spray drying is a method of producing a dry powder from a liquid or slurry by rapidly drying with a hot gas. Preferred method of drying of many thermally-sensitive materials such as foods and pharmaceuticals. A consistent particle size distribution is a reason for spray drying …
3. Therefore, a synchronous motor can be made to carry the mechanical load at constant speed and at the same time improve the power factor of the system. Synchronous motors are generally of the salient pole type. A synchronous motor is not self-starting and an auxiliary means has to be used for starting it. We use either induction motor principle or a …

14. Negative Phase contrast: • The background light is phase shifted -90° by passing it through a Phase shift ring. This eliminates the phase difference between the background and the scattered light. • To further increase contrast, the background is dimmed by a gray filter ring Positive phase contrast: • the background light is instead phase shifted by +90°.
