Explanation: radial conduction formula used

For steady-state radial conduction through cylindrical insulation (per unit length):

Q' = 2 * π * k * (Ti - To) / ln(r2 / r1)

Where r1 = outer radius of pipe (m), r2 = r1 + insulation thickness (m), k = conductivity (W/m·K), Q' in W/m.

Tip: If the browser cannot parse your `.xls`, please save Excel as .xlsx and re-upload. To exactly replicate your sheet's formulas, paste the sheet headers + 6–12 sample rows here or upload the .xlsx.
