"WebSep 1, 1993 · Even a fluid-temperature drop of 1 C or less from the pipe's inlet to its outlet is a sign of heat loss. This raises energy costs because heat must usually be added back to the fluid later. If the pipe-wall temperature is not unduly high, convection can be assumed to be the main cause of heat loss. A simple method quantifies this heat loss. " - Heat loss in insulated pipe calculator
