The movement of air in the vertical or main vent flues shouldnot be less than 6 feet per second. With an arrangement of theflues as described above, if properly constructed, this velocity,or even a greater, should be easily obtained. Make the register openings of such sizes that the velocityof the air through them will not be more than one half that inthe vertical duct, or in other words, not more than 3 feet per VENTILATION 223 second. If this schedule is adhered to, no perceptible draughtsAvill abound or be felt by the occupants of a room. Wlien seniidirect radiators are used for warming the enter-ing air, the dampers may be adjusted to suit the state of theweather. With indirect radiation the registers should equal insize and open area those used for foul air. Definite results as to
