To quickly assess the difficulty of the text, read a short excerpt:
From these examples it will be perceived that the amount of ventilation in mines, and, therefore, the safety, health, and comfort of the workmen employed in them, depend almost entirely upon the amount of friction that the air meets with, under any mode of ventilation we may employ ; and hence, the great importance of understanding the general laws and principles upon which the friction of air in mines depends, so that we may know how to reduce such friction to its lowest possible amount, and b...y this means obtain the greatest quantity of air, from any ventilating power we may employ.
Digitized by LjOOQ IC Oir THl FRICTION OF AIR IN MINES.
The amount of friction is reckoned or estimated by the amount of the pressure or force required to overcome it.
Numerous experiments have been made to find out the laws that govern the friction of air and gases, both in pipes having an uniform section, and, to a less extent, in the irregular air-ways of mines. By these experiments, the following laws have been found to hold good in prac- tice.
