Abstract (in english)
   The interpretation of the permeability of sandy rocks when the rock consists of angular grain is evaluated in this contribution. It is all set on these tasks: behaviour of the rock as a filter, calculation of total porosity of the rock being consisted of angular grains, classification of three various total porosities for angular grains and, finally, determination of the upper and lower limits for the estimated intergranular permeability both for the oval and angular grains. The expression of the temperature relationship of the water dynamic viscosity being in tabelar form into the semianalytic form being more suitable for computerising. As well as calculation of the methan dynamic viscosity for given temperature and pressure are described here
