13 Basics of Modes of Heat Transfer Calculators

Thermal Resistance of Spherical Wall
Go Thermal Resistance of Sphere Without Convection = (Radius of 2nd Concentric Sphere-Radius of 1st Concentric Sphere)/(4*pi*Thermal Conductivity*Radius of 1st Concentric Sphere*Radius of 2nd Concentric Sphere)
Radiation Thermal Resistance
Go Thermal Resistance = 1/(Emissivity*[Stefan-BoltZ]*Base Area*(Temperature of Surface 1+Temperature of Surface 2)*(((Temperature of Surface 1)^2)+((Temperature of Surface 2)^2)))
Radial Heat Flowing through Cylinder
Go Heat = Thermal Conductivity*2*pi*Temperature Difference*Length of Cylinder/(ln(Outer Radius of Cylinder/Inner Radius of Cylinder))
Heat Transfer through Plane Wall or Surface
Go Heat Flow Rate = -Thermal Conductivity*Cross Sectional Area*(Outside Temperature-Inside Temperature)/Width of Plane Surface
Radiative Heat Transfer
Go Heat = [Stefan-BoltZ]*Body Surface Area*Geometric View Factor*(Temperature of Surface 1^4-Temperature of Surface 2^4)
Rate of Convective Heat Transfer
Go Heat Flow Rate = Heat Transfer Coefficient*Exposed Surface Area*(Surface Temperature-Ambient Air Temperature)
Total Emissive Power of Radiating Body
Go Emissive Power per Unit Area = (Emissivity*(Effective Radiating Temperature)^4)*[Stefan-BoltZ]
Thermal Diffusivity
Go Thermal Diffusivity = Thermal Conductivity/(Density*Specific Heat Capacity)
Radiosity
Go Radiosity = Energy Leaving Surface/(Body Surface Area*Time in seconds)
Thermal Resistance in Convection Heat Transfer
Go Thermal Resistance = 1/(Exposed Surface Area*Co-efficient of Convective Heat Transfer)
Overall Heat Transfer based on Thermal Resistance
Go Overall Heat Transfer = Overall Temperature Difference/Total Thermal Resistance
Temperature Difference using Thermal Analogy to Ohm's Law
Go Temperature Difference = Heat Flow Rate*Thermal Resistance
Ohm's Law
Go Voltage = Electric Current*Resistance
