Therefore the condition {d) becomes:

In this expression we introducé for the nx, p and the n their values as they were empirically determined, for Q the values from Table 16; we then get

C — 0.892.

With this value formula (14) of page 25 and Table 16 lead at once to the following table for the qc.

Table 17.

Table of qc = CQ . {h — 0.685).
