Heat Transfer Coefficient

Heat Transfer Coefficient is used in measuring the transition of thermal energy from a hotter object to a cooler object (heat transfer). It is a ratio of the heat transfer rate or heat flux and the temperature difference which act as a driving force for the heat to transfer in such a way that the both the object and its surroundings reach to an equilibrium condition. Heat transfer between object in proximity with a temperature difference can never be stopped; it can only be slowed. Heat transfer coefficient is the inverse of thermal insulance.

== Units and Measures ==

Heat transfer coefficient is the quantity of heat that passes in unit time through unit area of a plate of particular thickness when it’s opposite faces differ in temperature.

Following are the units of heat transfer coefficient: * SI Units: watt per square-meter kelvin (W /m²•K) * Imperial Units: British thermal unit per hour Square feet degree Fahrenheit (Btu /ft²•°F•h)
