Study on the ventilation resistance of timbered airways (II)

Journal Article:

Abstract

From the results of a model study described in a previous paper (I), (Vol.23, No.4), a timber factor Kr is determined as a specific parameter for type of timber and as a function of spacing ratio d/e where d and e are the spacing and the height of sets respectively. A general formula for the determination of the friction coefficient of timbered airways is also proposed.
