Copper Tubes - Uninsulated Heat Losses

Heat loss from uninsulated copper pipes - dimensions ranging 1/2 - 4 inches. Calculate heat loss at various temperature differences between pipe and ambient air.

Copper Tubes - Uninsulated Heat Losses

Heat loss from uninsulated copper pipes - dimensions ranging 1/2 - 4 inches.

Note that temperature difference is used - and that 1 °C of temperature difference equals to 1.8 °F temperature difference.
