Excerpt from Pulp and Paper Magazine of Canada, 1916, Vol. 14 It has always been known that the consumption of a great amount of power will, produce pulp of a greater strength. The strength as represented by Mullen or Schopper tests increases with increasing power con sumption per ton. The relation between horsepower con sumption per ton of pulp per meter of breaking length of paper made from it, and the power consumption in grinding a ton of the pulp is also shown. At low values of power consumption greater strength is produced per horsepower than at high value. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
