For two or more cylinders of the same diameter working on the one shaft multiply the horse-power obtained from the single cylinder by the number of cylinders.

For double or triple compound engines condensing or non-condensing multiply the horse-power obtained by the applied rule, using the high pressure cylinder diameter, by the number of cylinders.

In the case of an engine to which the above rules do not apply the actual horse-power transmitted through the shaft will be taken as the horse-power.
