Thermal Resistance for Convection at Inner Surface Solution

STEP 0: Pre-Calculation Summary

Formula Used

Thermal Resistance = 1/(Inside Area*Inside Convection Heat Transfer Coefficient)
R_th = 1/(A_inside*h_inside)
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.
Inside Area - (Measured in Square Meter) - Inside Area is defined as the space inside the shape. It's a measure of 2-D space, and the units for area are squared ("length squared").
Inside Convection Heat Transfer Coefficient - (Measured in Watt per Square Meter per Kelvin) - Inside Convection Heat Transfer Coefficient is the coefficient of convection heat transfer at the inside surface of the body or object or wall, etc.

STEP 1: Convert Input(s) to Base Unit

Inside Area: 0.14 Square Meter --> 0.14 Square Meter No Conversion Required
Inside Convection Heat Transfer Coefficient: 1.35 Watt per Square Meter per Kelvin --> 1.35 Watt per Square Meter per Kelvin No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

R_th = 1/(A_inside*h_inside) --> 1/(0.14*1.35)

Evaluating ... ...

R_th = 5.29100529100529

STEP 3: Convert Result to Output's Unit

5.29100529100529 Kelvin per Watt --> No Conversion Required

FINAL ANSWER

5.29100529100529 ≈ 5.291005 Kelvin per Watt <-- Thermal Resistance
