SUMMARY
The discussion centers on calculating the flux density of salt in a horizontal tube measuring 10 cm, connecting seawater with a salinity of 30 g/l to freshwater with a salinity of approximately 0 g/l. It is established that an accurate answer cannot be derived solely from the provided data, emphasizing the necessity of additional information such as the diffusion coefficient of salt in water. The conversation highlights that velocity multiplied by concentration is not applicable due to the absence of advection in this scenario.
