It was a real breakthrough when I realized I was trying to test viscosity and not temperature. I have pictures at http://tinyurl.com/4cj4w if anyone is interested. I'm not sure what I'm going to do now. Lookin at the equations on the Engineering Tool Box, I think I can only expect about 16 GPM with the 55 GPM pump. I'd like to know how Meziere rates those pumps. I've seen lower flow and higher current across the board. Bob W.
