Yesterday, I discussed a very interesting topic with my colleagues regarding calories
Thread Content
It’s roughly like this: there is a pipeline for high-temperature gas, and last night the temperature at the source dropped, while it increased at the end of the pipeline. My colleague said that the flow rate had increased, while I said that although the flow rate had gone up, the temperature at the source had decreased; we started discussing it. Finally, I asked whether this increase at the end is short-term or long-term. I’m not sure if it’s clear enough. I hope you can help me figure this out
First, make assumptions through simulation, and then perform calculations to uncover the truth
The traffic must have increased. If the gas passes through the heater at a rate of 1 m3/h and then flows through a pipe to a distant location. Now that the flow rate has increased to 2 m3/h while the heater’s power remains unchanged, the temperature at the heater will inevitably drop. But the heat carried away by the gas has increased
Your colleague is smarter than you; you tend to get stuck in details
If heat loss is taken into account, it becomes clear that the final value equals the initial value minus the heat loss; if the heat loss is low, the final value increases
