Build question #1

[Choady]

I have a question regarding my liebig..any positive feedback is much appreciated.
I want to use a 15.5 keg with a 3.5 ft piece of 2" copper for the tower. Then a 90° to a 1.5ft of 2" copper for the lyne arm. Finally, a 90°to a 2"-1" reducer with 4 ft of 1" copper pipe where my liebig will be. Im wanting to build the liebig with 2" pvc around the 1" copper @ 2-3 ft. And heat using firewood.
My question is regarding the liebig...will it be sufficient enough to cool the product using a water hose temp unknown?
