Thanks, I understand that. I have a data logger, temperature probes and a bucket and a stop watch. Empirical values are great and useful, but checking to see if predicted values are observed is a lot more fun and rewarding. I did figure its about three hours to replace the entire mass, but...

Thanks edgepflow; I will check out the solution I come up with and let you know what I get. egg84: I am not familiar with working with heat exchangers, and did not realize you can set them at different temperatures. If I had to guess (and it's only a guess) getting the pool to the...

thanks for the info and the reply. I do remember equations of the form dT/dt = k (TH-TL) basically the rate of T temp change with respect to time is proportional to high temp - low temp. Do you know if this takes into account if same water is pumped back in, or if it is replacing lost...

I've been out of school for about 19 years and would like to solve a diff. eqn. If someone can point me toward the right equation that would be great. I will look for it as well and will try to solve the problem as well. If someone else finds info, I can use it to verify my findings. Thanks...
