STEP 1: Convert Input(s) to Base Unit

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
Inside Diameter: 0.047746 Meter --> 0.047746 Meter No Conversion Required
Heat Transfer: 2 Watt --> 2 Watt No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

L = k_e*pi*(t_i-t_o)*(D_o*D_i)/q --> 10*pi*(273.0367-273)*(0.05*0.047746)/2

Evaluating ... ...

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.
