| coil length | dimension of the face of the coil in the
direction of the bare tubes or finned tubes, or both, exposed to the flow of
air |
| | |
| coil width |
dimension of the face of the coil exposed to the
flow of air perpendicular to the direction of the tubes |

| coke | solid substance remaining after the partial
burning of coal in an oven distillation or in a retort. |

| Colburn heat transfer equation |
dimensionless heat
transfer equation used in calculating natural convection movement of heat from
vertical surfaces or horizontal cylinders to fluids (gases or liquids) flowing
past these surfaces. The symbol is jH. |
| | |
| Colburn mass transfer equation | dimensionless mass
transfer equation consisting of the Sherwood number divided by the Reynolds
number and the Schmidt number to the 1/3 power. The symbol is jD |

| cold box | in a gas separation unit, the insulated section
which contains the low-temperature heat exchangers and distillation columns |
| | |
| cold chain | continuity of means successively employed to
provide the refrigerated preservation of perishable foodstuffs from the
production to the consumption stage |
| | |
| cold injury (low-temperature injury) |
storage at a temperature below which
physiological disorder in produce will manifest itself. This temperature will
vary with the produce. |

| cold room (cold chamber) |
insulated structure served by a refrigerating
system. |
| | |
