Question
Based on the picture above, make a schematic and determine the average temperature difference over the entire length of the tube (ATLM). (value 25)
The image shows a schematic of a cylindrical pipe through which water is flowing. The pipe is subjected to external air flow. Here's a detailed explanation of the elements depicted: - **Pipe Dimensions and Conditions:** - The pipe has a **diameter (D)** of 0.05 meters. - The length of the pipe is indicated by **L**. - **Temperature and Medium Inside the Pipe:** - Water flows inside the pipe, entering with an **inlet temperature (\( T_{m,i} \))** of 70°C. - **Temperature on Pipe Surface and Surrounding Air:** - The **surface temperature (\( T_{m,o} \))** of the pipe is 30°C. - The surrounding **air temperature (\( T_{\infty} \))** is 15°C. - **Medium Surrounding the Pipe:** - Air is flowing externally around the pipe. This diagram is useful for studies involving convective heat transfer between the fluid inside the pipe and the surrounding environment, highlighting the impact of different temperatures on the system.
