The discussion revolves around the relationship between pipes and temperature, specifically focusing on the linear expansion of a highway due to heat from water in pipes. The problem involves calculating the length change of a 10 km highway when influenced by hot water.
Some participants have offered guidance on how to approach the problem by suggesting the use of assumptions and relevant equations. However, there remains uncertainty about the exact wording of the problem and its implications.
There are indications of missing information and potential ambiguities in the problem statement, particularly regarding the phrase "after passing pipes with hot water." Participants are encouraged to clarify these aspects.
Is this really the exact statement of the problem? What does "after passing pipes with hot water" even mean?deynak said:Problem Statement: By how much can a 10 km highway lengthen after passing pipes with hot water?
a) 100m; b) 50m; c) 25m; d) 10m.
Relevant Equations: ΔL = L x a x ΔT
ΔL = total change in the length of the pipe [mm]
L = original pipe length [m]
a = linear expansion coefficient
ΔT = difference in temperature [°C]
It seems for me that something is missing on the question. Actually, I do not know where to start.
