WebMar 24, 2008 · Poolking, Mar 24, 2008. #4. Poolking New Member. Sorry there's a mistake in my first reply. As r1 is the two legs of the ring measured in series. Then r1 is 1/2 of R1+R2. The main equation as I mentioned earlier is (r1 + r2)/4 = R1 + R2. This presumes the ring and cps sizes are the same. Poolking, Mar 24, 2008.
