Hi i saw this page http://www.sintecoptronics.com/yihong/cwco2.htm about an helium-free CO2 Laser
What's the power of the water pump ( kw ) if we want to have a cooling water = 3t/hr ?
What's the power of the vaccuum pump if we want to have to have a pressure = 60 torrs ?
Thanks a lot for your answer

So at 8.34 pounds/ gallon three tons = 6000/lbs
6000/8.34= about 720 gallons
Which would easily be done by a pump that has 1-2 horse power so about 750 watts-1.5 Kw.
Any HVAC vacuum would go to 60 torr easily.
All information found using google.
