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.
Thermal expansion is the increase in size or volume of a substance when its temperature rises. This can cause pipes to expand and contract, potentially leading to cracks or leaks.
As temperature increases, the molecules in water gain energy and move faster, causing the water to flow more quickly through pipes. Conversely, colder temperatures can cause the water to flow more slowly.
Yes, extreme temperatures can cause pipes to expand or contract beyond their limits, leading to cracks or bursts. This is especially common in freezing temperatures, as the water inside pipes can freeze and expand, causing them to burst.
Yes, most pipes are designed to withstand a range of temperatures, typically between 32°F (0°C) and 212°F (100°C). However, the ideal temperature for pipes may vary depending on the material and purpose of the pipes.
Extreme temperature changes, such as frequent fluctuations between hot and cold, can put stress on pipes and potentially shorten their lifespan. Additionally, extremely high or low temperatures can cause damage to pipes over time.
