Heat Transfer Coefficient

The heat transfer coefficient is the proportionality constant between the heat flux and the thermodynamic driving force for the flow of heat.

The heat transfer coefficient equals the heat transferred divided by the transfer surface area, the time interval and the temperature difference.

Formula

QuantityVariable["h", "HeatTransferCoefficient"] == QuantityVariable["Δ​Q", "Heat"]/(QuantityVariable["A", "Area"]*QuantityVariable["Δ​t", "Time"]*QuantityVariable["Δ​T", "TemperatureDifference"])

symbol description physical quantity
h heat transfer coefficient "HeatTransferCoefficient"
A heat transfer surface area "Area"
Δ​Q heat transferred "Heat"
Δ​t time interval "Time"
