Rate of water cooling through copper pipe?

Click For Summary
SUMMARY

The discussion focuses on calculating the length of 3/8 inch diameter copper tubing required to cool 2000ml of water from 80 degrees Celsius to ambient room temperature of 20 degrees Celsius. With a heat dissipation requirement of 500W and a flow rate of 0.13 liters per minute, approximately 70 meters of copper tubing is necessary to achieve the desired cooling effect. This calculation is crucial for designing an effective custom PC water cooling system.

So say I have a tank of water of about 2000mls which is at around 80 degrees celsius and is pumped around a copper system which is 3/8th inch thick pipe. how many meters would the water have to travel through copper pipe to return to ambient room temperature of about 20 degrees celsius. any help is much appreciated. this does relate to a real world idea i have at the moment for a custom pc water cooling system.

Assuming you mean 3/8 inch outside diameter copper tubing, and you need to dissipate, say, 500W of heat. At a flow rate of 0.13 liters/min, cooling the water from 80oC to 24oC in a 20oC room, you'll need about 70 meters of tubing.
