Cavitation tests

marine

Cavitation tests are performed in a cavitation tunnel using a dummy afterbody model and simulated full-scale wake-field or a full model.

Cavitation tunnel

marine

A facility used for propeller cavitation tests. This is a vertical water circuit with large diameter pipes. A parallel inflow is established.

Ceiling systems

marine

Suspended metal ceilings are suitable for public spaces (restaurants, shops, and theatres), cabins and corridors, storage rooms and offices.

Ceilometer

energy

A ceilometer is a device that uses a laser or other light source to determine the height of a cloud ceiling or cloud base.

Cellulosic ethanol

energy

Cellulosic ethanol is ethanol (ethyl alcohol) produced from cellulose (the stringy fiber of a plant) rather than from the plant's seeds or fruit.

Celsius

energy

The degree Celsius (°C) is a unit of temperature on the Celsius scale, a temperature scale originally known as the centigrade scale.

Cement carrier

marine

A single-skin or double-skin bulk carrier provided with a cement loading and discharging plant.

Cement carrier KEDAH CEMENT II

marine

According to The Motor Ship May 1996 The self-loading/discharging cement carrier KEDAH CEMENT II was built by Pan-United Shipyard, Singapore.

Centimetre–gram–second system of units

energy

A variant of the metric system based on the centimetre as the unit of length, the gram as the unit of mass, and the second as the unit of time.

Centistokes

marine

An established unit used for the measurement of kinematic viscosity. The accepted SI unit is m2/s and 1cSt = 10-6 m2/s.

Central control station (SOLAS)

marine

A control station in which the following control and indicator functions are centralized:

Central Cooling Water System

marine

Most cooling systems are made as central cooling ones, which means that there is only one or two large plate heat exchangers equipped with titanium plates.

Central heating

energy

Central heating is used to heat many connected areas such as the rooms of a house.

Centralized priming system

marine

It consists of a suitably constructed tank which is maintained automatically under a vacuum by air exhausting units, with connections leading to the tank from each of the pumps concerned.

Centralized pumping system

energy

Flow centers located centrally in a ground source system that produce flow to all heat pump units in that system.

Centre of buoyancy

marine

The centre of gravity of the displaced water. That is, the geometrical centre of the underwater part of the ship.

Centre of flotation

marine

The geometric centre of the waterplane on which a vessel floats. A vessel pitches, or rotates (about a transverse axis) through this point, when moved by an external force.

Centre of gravity

marine

The point at which the total weight of all the items which make up a vessel total weight may be considered as concentrated.

Centre of lateral resistance

marine

The point through which the resultant of resistance of the immersed hull to lateral motion passes.

Centreline

marine

A line of symmetry between the port and starboard sides of any vertical section or any horizontal section. The middle line of the ship extending from stem to stern at any level.
