Area of thermal contact Solution

STEP 0: Pre-Calculation Summary

Formula Used

Thermal Contact Area = (Specific Heat*Mass)/(Heat Transfer Coefficient*Thermal Time Constant)
A = (k*m)/(h_coeff*𝜏)
This formula uses 5 Variables

Variables Used

Thermal Contact Area - (Measured in Square Meter) - Thermal Contact Area is the interface region between two contacting surfaces where thermal conduction occurs.
Specific Heat - (Measured in Joule per Kilogram per K) - Specific Heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius.
Mass - (Measured in Kilogram) - Mass is the quantity of matter in a body regardless of its volume or of any forces acting on it.
Heat Transfer Coefficient - (Measured in Watt per Square Meter per Kelvin) - 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.
Thermal Time Constant - (Measured in Second) - 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.

STEP 1: Convert Input(s) to Base Unit

Specific Heat: 35.5 Joule per Kilogram per K --> 35.5 Joule per Kilogram per K No Conversion Required
Mass: 35 Kilogram --> 35 Kilogram No Conversion Required
