(Q = V / τ) by means of the stopwatch and the measuring capacity.

For this purpose determine the volume of water V which filled the
w
measuring capacity during the time τ. (The stable water filtration
regime is controlled by the repeated water flow rate measurement).

Conduct the experiments 5 – 7 times under different pressure
differences.
4.4.6 Draw the graph of dependence Q = f (ΔР) (for control the

linearity of water filtration).
Water filtration through the rock sample must be according to
the linear law that is the graph of dependence Q = f (ΔР) must be a
straight line.
