Cova:
Yes I agree with your clarification. I just couldnt put it into words that well yesterday
gmat:
I am not sure about this but I have a feeling that NONE of us like Differental Equations (Lord knows I hate them!!!
) However your right, we do have to deal with them unless we all want to stay in "theory" world.
As for the faster flow throught a radiator = more heat disappation; I am still not convinced. Could be true but still has some holes in it.
One other thing. I have been reading around the threads and mentioning that we need to heat the water before it enters the radiator in order to make the radiator more efficent.....
Here is my take on that: YES a radiator WILL be more efficient the higher the Delta-T between ambient air and the water temp. However, making the radiator more efficent by heating the water more than necessary only adds more heat to the system and thus heats the whole system up. This is obviously bad; heat = bad
Our radiators in our system WILL only be running at say 10% efficency because we want our water temps AS CLOSE TO AMBIENT AS POSSIBLE!!! A radiator running at say 50% efficency could remove say 2 degrees from a 15 degree delta-T water but that still leaves 13 degrees delta-T which goes right back to the block and gets more heat. OUr Radiators running at say 10% efficency will only be able to remove say 1 degree from a 8 degree delta-T which leaves only 7 degrees delta-T water.
NOTE: DO NOT HOLD ME TO THESE NUMBERS!! This is for theory example ONLY! Just to give us an IDEA of what is going on, not the actual figures.
Alright another wave of friendly flames come forth!
