               GROUP  2  SYSTEMS
                 The larger and usually more complex type of oil-circulatory system, used for both lubrication and cooling, falls into two
               distinct classes. The first type, known as the self-contained system, is usually limited in size by  the weights of the components.
                For  this reason  the storage capacity  of  this type  does not  usually  exceed  1000 gal. The second type covering the larger
                systems has  the main components laid  out at floor level, e.g.  in  the oil cellar.  The detailed  design considerations  of  the
                main components are discussed elsewhere, but in laying out the system the possible need for the equipment in Table 18.1
                should  be considered.
