Concerning the partial dT over dx. You said it's the difference of temperature over dx= 2. But 2 is the size of just one part of the pool. Or, dT changes over 2 parts of the pool. Therefore, we must divide the difference on 4. What do you think?

Still i don't get it why at time = 0 the first temp. is equal to 25, and then when we have time = 1, the temperature on first part of pool is equal to 28. What happend? Did we heat up at time = 1 the first part of the pool by 3 degrees?

Second question:
The local change at time = 1 is 4 degrees. But when you take the temporal change (still to the time = 1) you take a change of temperature on the pool with temperatures 25 and 28. Why?

Please help me understand this problem <3

Best regards from Poland! 😀

thank you for this video, it's a nice explanation. but i would suggest to use a sketchpad or something to write the calculations you are doing, that would make things easier to follow

Great example, demonstrating pde being applied on a practical case.
It may not be possible for you to expand it for for further up to 4th, 5th or 6th element and with a different velocity i.e 4 m/s
so if you could pl. suggest a book or reference where this could be studied in more detail. thx
