10Developing mathematical models describing pipe (or duct) temperature is of great 11 importance, since pipes are unavoidable elements in most (hydraulic) heating systems, in 12 which some heat transfer fluid flows/circulates between neighbouring working components 13 (such systems are district, central or solar heating systems, etc.). 14In the present study, the Newton's law of cooling is completed with a recent explicit equation
