## Temperature inside hollow cylinder at given radius between inner and outer radius Solution

STEP 0: Pre-Calculation Summary
Formula Used
T = ((qG/(4*k))*((r₂)^2-(r)^2))+To+((ln(r/r₂)/ln(r₂/r₁))*((qG/(4*k))*((r₂)^2-(r₁)^2)+(To-Ti)))
This formula uses 1 Functions, 7 Variables
Functions Used
ln - Natural logarithm function (base e), ln(Number)
Variables Used
Internal heat generation - Internal heat generation is defined as the conversion of electrical, chemical, or nuclear energy into heat (or thermal) energy which leads to a rise in temperature throughout the medium. (Measured in Watt Per Cubic Metre)
Thermal Conductivity - Thermal Conductivity is the rate at which heat passes through a specified material, expressed as the amount of heat that flows per unit time through a unit area with a temperature gradient of one degree per unit distance. (Measured in Watt per Meter per K)
Outer Radius of Cylinder - The Outer Radius of Cylinder is a straight line from the center to the Cylinder's base to outer surface of the Cylinder. (Measured in Meter)
Given radius - Given radius is the radial distance to the point or plane up to which the value of the desired variable will be calculated. (Measured in Meter)
Outer surface temperature - Outer surface temperature is the temperature at the outer surface of the wall (either plane wall or cylindrical wall or spherical wall, etc). (Measured in Kelvin)
Inner Radius of Cylinder - The Inner Radius of Cylinder is a straight line from the center to the Cylinder's base to inner surface of the Cylinder. (Measured in Meter)
Inner surface temperature - Inner surface temperature is the temperature at the inner surface of the wall (either plane wall or cylindrical wall or spherical wall, etc). (Measured in Kelvin)
