Pipes and Cylinders - Conductive Heat Loss
Calculate conductive heat loss through uninsulated or insulated pipes and cylinders using thermal conductivity and temperature differences.
Pipes and Cylinders - Conductive Heat Loss
Calculate conductive heat loss through the wall of uninsulated or insulated cylinders and pipes.
Uninsulated Cylinder or Pipe
Q = 2π L (tᵢ - tₒ) / (ln(rₒ / rᵢ) / k)
Insulated Cylinder or Pipe
Q = 2π L (tᵢ - tₒ) / ((ln(rₒ / rᵢ) / k) + (ln(rₛ / rₒ) / kₛ))
Insulated Cylinder or Pipe with Convective Heat Resistance
Q = 2π L (tᵢ - tₒ) / (1 / (hc rᵢ) + (ln(rₒ / rᵢ) / k) + (ln(rₛ / rₒ) / kₛ))
