## Thermal Resistance for Convection at the Inner Surface Solution

STEP 0: Pre-Calculation Summary
Formula Used
Thermal Resistance = 1/(Inside Area*Inside Convection Heat Transfer Coefficient)
Rth = 1/(Ainside*hinside)
This formula uses 2 Variables
Variables Used
Inside Area - 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"). (Measured in Square Meter)
Inside Convection Heat Transfer Coefficient - Inside Convection Heat Transfer Coefficient is the coefficient of convection heat transfer at the inside surface of the body or object or wall, etc. (Measured in Watt per Meter² per K)
STEP 1: Convert Input(s) to Base Unit
Inside Area: 13 Square Meter --> 13 Square Meter No Conversion Required
Inside Convection Heat Transfer Coefficient: 1 Watt per Meter² per K --> 1 Watt per Meter² per K No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Rth = 1/(Ainside*hinside) --> 1/(13*1)
Evaluating ... ...
Rth = 0.0769230769230769
STEP 3: Convert Result to Output's Unit
0.0769230769230769 Kelvin per Watt --> No Conversion Required
0.0769230769230769 Kelvin per Watt <-- Thermal Resistance
