• Transformation ratio determines the voltage transformation between the primary and secondary windings of a transformer.

• It is calculated as the ratio of the number of turns in the primary winding to the number of turns in the secondary winding.

• For example, if a transformer has ...read more

Parts of pumps and motors include impeller, casing, shaft, bearings, and seals.

• Impeller: Rotating component that generates the flow in a pump.

• Casing: Encloses and supports the impeller and other parts of the pump.

• Shaft: Transfers power from the motor to the impeller.

• Bearings: Support and align the shaft within the pump.

• Seals: Prevent leakage of fluid from the pump.

Parts of pumps and motors include impeller, casing, shaft, bearings, and motor housing.

• Impeller: Rotating component that generates the flow within the pump.

• Casing: Encloses the impeller and directs the flow of fluid through the pump.

• Shaft: Transfers the rotational energy from the motor to the impeller.

• Bearings: Support the shaft and reduce friction during rotation.

• Motor housing: Encloses the motor and provides protecti
