STEP 0: Pre-Calculation Summary

Formula Used

Overall Heat Transfer = Overall Temperature Difference/Total Thermal Resistance
q_overall = ΔT_Overall/ΣR_Thermal
This formula uses 3 Variables

Variables Used

Overall Heat Transfer - (Measured in Watt) - Overall Heat Transfer is defined as the ratio of Overall temperature change to the total thermal resistance.
Overall Temperature Difference - (Measured in Kelvin) - Overall Temperature Difference is defined as the difference between final temperature and initial temperature.
Total Thermal Resistance - (Measured in Kelvin per Watt) - Total Thermal Resistance is a heat property and a measurement of a temperature difference by which an object or material resists a heat flow.

STEP 1: Convert Input(s) to Base Unit

Overall Temperature Difference: 55 Kelvin --> 55 Kelvin No Conversion Required
Total Thermal Resistance: 19.68 Kelvin per Watt --> 19.68 Kelvin per Watt No Conversion Required

What is Heat Transfer?

Heat transfer is a discipline of thermal engineering that concerns the generation, use, conversion, and exchange of thermal energy between physical systems. Heat transfer is classified into various mechanisms, such as thermal conduction, thermal convection, thermal radiation, and transfer of energy by phase changes.

Define Thermal Conductivity & Factors affecting it?

Thermal conductivity is defined as the ability of a substance to conduct heat.
Factors Affecting The Thermal Conductivity are:
Moisture, Density of material, Pressure, Temperature & Structure of material.
