Outside Area given Outer Thermal Resistance Solution

STEP 0: Pre-Calculation Summary

Formula Used

Outside Area = 1/(External Convection Heat Transfer Coefficient*Thermal Resistance)
A_outside = 1/(h_outside*R_th)
This formula uses 3 Variables

Variables Used

Outside Area - (Measured in Square Meter) - Outside Area is the space outside the shape. It's a measure of 2-D space, and the units for area are squared ("length squared").
External Convection Heat Transfer Coefficient - (Measured in Watt per Square Meter per Kelvin) - External Convection Heat Transfer Coefficient is the proportionality constant between the heat flux and the thermodynamic driving force for the flow of heat in case of convective heat transfer.
Thermal Resistance - (Measured in Kelvin per Watt) - 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

External Convection Heat Transfer Coefficient: 9.8 Watt per Square Meter per Kelvin --> 9.8 Watt per Square Meter per Kelvin No Conversion Required
