so as to give an effective working temperature in the building of about 72°F.

A table below gives D

c as a function of the stack diameter at a stack height

The friction loss for any height can be obtained from this table by
multiplying by 0.01H. It can be seen that the losses arc small in general

and after the losses in the ducts have been estimated it will be possible

to choose a blower to do the job. If the stack is assumed to be 110 feet

with a 6 foot diameter than the loss will only be 0.059 inches of water,

Blowers develop with ease in the capacity needed pressure differences of

2" of H

20. The difference between this and the loss in stack is certainly
