When, in addition to the friction mentioned, it is pointed out that in the majority of
churches and halls by far the largest volume of air which gains access to the
building comes in at the top, and, by so doing, reduces the actual ventilating ...

and when this fact is duly weighed, how fatal to the introduction of fresh air is the
practice of closing every chink and crack by india-rubber tubing ! For if by this ...

From the above deductions it is clear that three-fourths of the ventilating pressure
is generally used up in friction due to the small apertures through which air is
forced into a building. Whilst this is true in most cases, great care must be ...

Recent experiments with kites fitted with recording instruments, have shown that
the velocity of the wind is generally twice as great at the altitude of 1,ooo feet as it
is in the open country near the ground level. Again, the friction caused by the ...
