Thermal Resistance for Convection at the Outer Surface Solution

STEP 0: Pre-Calculation Summary
Formula Used
Thermal Resistance = 1/(External Convection Heat Transfer Coefficient*Outside Area)
Rth = 1/(houtside*Aoutside)
This formula uses 2 Variables
Variables Used
External Convection Heat Transfer Coefficient - 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. (Measured in Watt per Meter² per K)
Outside Area - 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"). (Measured in Square Meter)
STEP 1: Convert Input(s) to Base Unit
External Convection Heat Transfer Coefficient: 10 Watt per Meter² per K --> 10 Watt per Meter² per K No Conversion Required
Outside Area: 15 Square Meter --> 15 Square Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Rth = 1/(houtside*Aoutside) --> 1/(10*15)
Evaluating ... ...
Rth = 0.00666666666666667
STEP 3: Convert Result to Output's Unit
0.00666666666666667 Kelvin per Watt --> No Conversion Required
FINAL ANSWER
0.00666666666666667 Kelvin per Watt <-- Thermal Resistance
