A = 10.3541666666667m²

LAST Step Rounding Answer

∴

A = 10.3542m²

Area of thermal contact Formula Elements

Variables

Thermal Contact Area

Thermal Contact Area is the interface region between two contacting surfaces where thermal conduction occurs.

Symbol: A

Measurement: AreaUnit: m²

Note: Value should be greater than 0.

Formulas to find Thermal Contact Area

Specific Heat

Specific Heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius.

Symbol: k

Measurement: Specific Heat CapacityUnit: J/(kg*K)

Note: Value should be greater than 0.

Formulas to find Specific Heat

Mass

Mass is the quantity of matter in a body regardless of its volume or of any forces acting on it.

Symbol: m

Measurement: WeightUnit: kg

Note: Value should be greater than 0.

Formulas to find Mass

Heat Transfer Coefficient

Heat Transfer Coefficient is the heat transferred per unit area per kelvin. Thus, area is included in the equation as it represents the area over which the transfer of heat takes place.

Symbol: h_coeff

Measurement: Heat Transfer CoefficientUnit: W/m²*K

Note: Value should be greater than 0.

Formulas to find Heat Transfer Coefficient

Thermal Time Constant

Thermal Time Constant refers to the time it takes for a system or material to reach a certain percentage (usually 63.2%) of its final temperature after experiencing a change in heat input.

Symbol: 𝜏

Measurement: TimeUnit: s

Note: Value should be greater than 0.
