4.4.7 Put the results of experiments into table 4.1.
4.4.8 The magnitudes of water viscosity depending on the
temperature are given in table 4.2.
4.4.9 Calculate the coefficient of permeability of the rock sample

for water by means of equation (4.1) and the average coefficient of
permeability of the rock sample for water as well.
