thermal conductance

n.
1. A measure of the ability of an object to allow the flow of heat from its warmer surface through the object to its colder surface, determined as the heat energy transferred per unit of time divided by the temperature difference between the two surfaces, expressed in watts per kelvin. The conductance of an object equals the conductivity of its material times its surface area (cross-section) divided by the distance between the two surfaces (thickness).
2. The reciprocal of thermal resistance, usually measured in units of watts per kelvin.

The final K-Value, Menshlickeit, translates literally as humanity and the 'human touch'.
The purpose of this investigation was to determine if the distribution ratio of moisture between the vapor and liquid phases of a refrigerant or K-value is significantly affected by the presence of a lubricant.
In contrast to a calibration factor based solely on the relationship between chamber response and activity, the ratio-based K-value is insensitive to variations in the electrometer response over time.
Because the sample set is small in this case, the K-value was selected uniformly as K=1 (corresponding to nearest-neighbor predictions), K=7, 14, 21, 28 (corresponding to different KNN prediction), and K=34 (corresponding to global prediction).
The relative level of [beta]-phase is usually described in terms of the K-value, which is defined by the relation proposed by Turner-Jones et al.
Thai Airways International Public Company Limited (THAI) on Monday said that with Kasikorn Bank Public Company Limited (Kabnk) it has introduced a K-Value Chain Solutions.
However, it has been difficult for barrier dielectrics to fulfill both the requirements of low k-value and perfect blocking properties because the latter property is usually diminished by reducing the k-value or essentially the film density.
In order to quantify water spreading and penetration, the k-value proposed by Shi and Gardner (2001) was calculated.
