pipe; therefore, you have to convert all elbows to an equivalent of pipe. To convert 90o and 45o elbows to equivalent feet of pipe use Chart 2. When figuring the feet of pipe count lateral type branches as 45o elbows . Flexhose has a lot of resistance de-pending on the corrugation . For this reason we suggest you keep hose to a minimum .

NOTE: Grinding balls and media are sold on a per pound basis, but ATTRITORS and DMQX-Mills are loaded by volume. Therefore, the more dense the media, the more pounds of media required. For instance, a machine requiring only 40 lbs. of stainless steel may require up to 80 lbs. of tungsten carbide.
