In a dwelling-house of two stories,no difference would 15e made in thesizes of radiators on the two floors;but in the case of a tall office build-ing, corrections would necessarily be made as above described. Where circulation coils are used, they should be of a form whichwill tend to produce a flow of water through them. Figs. OS, 00, and100 show different ways of making up and connecting these Figs. 98 and 100, supply pipes may be ether drops or risers; and. Fig. 97.
