Variables Used

Thermal Resistance with Convection - (Measured in Kelvin per Watt) - Thermal resistance with Convection is a heat property and a measurement of a temperature difference by which an object or material resists a heat flow.
Inside Convection - (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.
Area of Wall - (Measured in Square Meter) - Area of Wall refers to the surface area of the wall, which is the total amount of space that it occupies. It is typically measured in square units such as square feet or square meters.
Length - (Measured in Meter) - Length is the measurement or extent of something from end to end.
Thermal Conductivity - (Measured in Watt per Meter per K) - Thermal Conductivity is rate of heat passes through specified material, expressed as amount of heat flows per unit time through a unit area with a temperature gradient of one degree per unit distance.
External Convection - (Measured in Watt per Square Meter per Kelvin) - External Convection is the proportionality constant between the heat flux and the thermodynamic driving force for the flow of heat in case of convective heat transfer.

STEP 1: Convert Input(s) to Base Unit

Inside Convection: 1.35 Watt per Square Meter per Kelvin --> 1.35 Watt per Square Meter per Kelvin No Conversion Required
Area of Wall: 50 Square Meter --> 50 Square Meter No Conversion Required
Length: 3 Meter --> 3 Meter No Conversion Required
Thermal Conductivity: 10 Watt per Meter per K --> 10 Watt per Meter per K No Conversion Required
External Convection: 9.8 Watt per Square Meter per Kelvin --> 9.8 Watt per Square Meter per Kelvin No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

r_th = 1/(h_i*A_w1)+L/(k*A_w1)+1/(h_o*A_w1) --> 1/(1.35*50)+3/(10*50)+1/(9.8*50)

Evaluating ... ...

r_th = 0.0228556311413454

STEP 3: Convert Result to Output's Unit

0.0228556311413454 Kelvin per Watt --> No Conversion Required

FINAL ANSWER

0.0228556311413454 ≈ 0.022856 Kelvin per Watt <-- Thermal Resistance with Convection
