KELSON, KEELSON -- The
wrought-iron saddles or standards that support cylindrical boilers of the
Scotch marine type. Sometimes called boiler cradles.
Longitudinal strength member of a ship that forms the hull-plating
stiffeners.
KELVIN (K) -- The SI unit of thermodynamic temperature. The
measurements are made from absolute zero; the temperature interval corresponds
with that of the Celsius scale, so that the freezing point of water is 273.15
K
KEROSENE -- A petroleum fraction with a boiling range or
150°-300°C, relative density
0.78-0.82, flash-point not lower than 32°C; used in lamps and heating
appliances. Another type of kerosene (with higher volatility), known as
vaporizing oil, is used in some internal-combustion engines; and
kerosene-type fuels are of great importance for gas turbine and jet engines.
KILO -- Prefix denoting 1000; used in the metric system. E.g.
1 kilogram = 1000 grams.
KILOVAR (kVar) -- The unit of measure of reactive power; the
power supplied to most types of electromagnetic equipment, such as motors.
KILOVOLT AMPERE (kVA) -- A commonly used unit for expressing
the rating of a.c. electrical machinery. The volt-amperes of an electric
circuit are the mathematical products of the volts and amperes of the
client.
KILOWATT (kW) -- The electrical unit of power equal to 1,000
watts.
KILOWATT-HOUR (kWh) -- The basic unit of electric energy equal
to one kilowatt of power supplied to or taken from an electric circuit for one
hour. 1kWh = 3.6 MJ (Megajoule)
KINETIC ENERGY -- Energy available as a result of motion that
varies directly in proportion to an object's mass and the square of its
velocity.
KINETIC THEORY OF GASES -- The conception of gas molecules as
elastic spheres whose bombardment of the wall of the containing vessel due to
their thermal agitation causes the pressure exerted by the gas. The theory
gives a simple explanation of the gas law and has yielded valuable results
concerning gaseous viscosity and molecular dimensions.
KIP -- A unit of mass equivalent to 1000 lb
KNOTS -- A unit of speed equivalent to one nautical mile, 1852
m, per hour.
