Kalrez: Kalrez is a perfluoroelastomer material widely used in the manufacturing of seals and O-rings. It is produced by E.I. Dupont and is known for its exceptional resistance to a wide range of aggressive chemicals.

Kerosene: Kerosene is a combustible hydrocarbon commonly used as a fuel. It is also utilized as a low specific gravity testing fluid after a pump has been determined to be water-tight, allowing for effective leak testing.

Ketone: Ketone refers to a chemical group of organic compounds characterized by the presence of a carbonyl group attached to various alkyl groups. Ketones have diverse applications in different industries.

Key: A key is a small square piece of metal used to secure a rotating part onto a shaft, preventing independent rotation of the part relative to the shaft. Keys play a crucial role in maintaining the alignment and integrity of mechanical assemblies.

Keyway: A keyway is a slot or groove machined into a shaft to accommodate a key. It provides a precise location for the key, ensuring a secure connection between the shaft and the rotating part.

K factor: The K factor is a coefficient used to calculate friction loss in a system caused by fittings. Various tables are available that list specific fittings and their corresponding K factors. It is employed in equations to determine the overall pressure loss in a piping system.

Kiln: A kiln is a type of furnace used for drying, baking, or other thermal processes. It is commonly utilized to produce “kiln-dried wood,” which exhibits enhanced dimensional stability and is often used in pattern-making applications.

Kilowatt: A kilowatt is a unit of power equivalent to one thousand watts. The watt is the SI unit of power, defined as one joule per second. Kilowatts are commonly used to measure and express the power output of electrical devices or systems.

Kinematics: Kinematics is a branch of mechanics that focuses on the study of motion without considering the forces that cause it. It involves the analysis of displacement, velocity, and acceleration of objects or particles.

Kinetic energy: Kinetic energy refers to the energy possessed by an object due to its motion. In the context of pumps, the impeller imparts kinetic energy to the fluid as it rotates, and this energy is harnessed by the resistance created by the volute or other components of the pump.

kPa: kPa stands for kilopascal, which is a unit of measurement for pressure in the International System of Units (SI). It is defined as one thousand newtons per square meter. Approximately 100 kPa is equivalent to one atmosphere of pressure.

kV: kV stands for kilovolt, which is equal to one thousand volts. It is a unit of electrical potential difference in the SI system. A potential difference of one kilovolt imparts one joule of energy per coulomb of charge that passes through it.
