Thermal Resistance for Convection at Outer Surface Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

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.
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.
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").

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
Outside Area: 0.019 Square Meter --> 0.019 Square Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

R_th = 1/(h_outside*A_outside) --> 1/(9.8*0.019)

Evaluating ... ...

R_th = 5.37056928034372

STEP 3: Convert Result to Output's Unit

5.37056928034372 Kelvin per Watt --> No Conversion Required

FINAL ANSWER

5.37056928034372 ≈ 5.370569 Kelvin per Watt <-- Thermal Resistance
