D_i = q/(k_e*pi*(t_i-t_o)*D_o/L)
This formula uses 1 Constants, 7 Variables

Constants Used

pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288

Variables Used

Inside Diameter - (Measured in Meter) - Inside Diameter is the diameter of the inside surface.
Heat Transfer - (Measured in Watt) - Heat Transfer is defined as the movement of heat across the border of the system due to a difference in temperature between the system and its surroundings.
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.
Inside Temperature - (Measured in Kelvin) - Inside Temperature is the temperature of air present inside.
Outside Temperature - (Measured in Kelvin) - Outside Temperature is the temperature of air present outside.
Outside Diameter - (Measured in Meter) - Outside Diameter is the diameter of the outside surface.
Length - (Measured in Meter) - Length is the measurement or extent of something from end to end.

STEP 1: Convert Input(s) to Base Unit

Heat Transfer: 2 Watt --> 2 Watt No Conversion Required
Thermal Conductivity: 10 Watt per Meter per K --> 10 Watt per Meter per K No Conversion Required
Inside Temperature: 273.0367 Kelvin --> 273.0367 Kelvin No Conversion Required
Outside Temperature: 273 Kelvin --> 273 Kelvin No Conversion Required
Outside Diameter: 0.05 Meter --> 0.05 Meter No Conversion Required
Length: 3 Meter --> 3 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

D_i = q/(k_e*pi*(t_i-t_o)*D_o/L) --> 2/(10*pi*(273.0367-273)*0.05/3)

Evaluating ... ...

D_i = 104.079526817599

STEP 3: Convert Result to Output's Unit

104.079526817599 Meter --> No Conversion Required

FINAL ANSWER

104.079526817599 ≈ 104.0795 Meter <-- Inside Diameter

What is convection?

Convection is the process of heat transfer by the bulk movement of molecules within fluids such as gases and liquids. The initial heat transfer between the object and the fluid takes place through conduction, but the bulk heat transfer happens due to the motion of the fluid.
Convection is the process of heat transfer in fluids by the actual motion of matter.
It happens in liquids and gases.
It may be natural or forced.
It involves a bulk transfer of portions of the fluid.
