The heat loss from insulated copper pipes or tubes to surrounding air are indicated below. The heat loss is based on temperature difference 55 oC (99 oF) with insulation thickness 25 mm (1 inch) and conductivity coefficient k = 0.043 W/m oC (0.3 Btu in/ft2 hr oF).
|Nominal bore||Heat Loss|
- 1 W = 3.4 Btu/hr
- 1 ft (foot) = 0.3048 m
Heat loss from pipes, tubes and tanks - with and without insulation - foam, fiberglass, rockwool and more.
Heat transfer and heat loss from buildings and technical applications - heat transfer coefficients and insulation methods to reduce energy consumption.
Dimensions of pipes and tubes, materials and capacities, pressure drop calculations and charts, insulation and heat loss diagrams.
Hot and cold water service systems - design properties, capacities, sizing and more.
