So we have for y =r 0,75 : 



Here too the curve />=f(v) is almost rectilinear for v^^0,6vk', 

 iiaj even for ?;=: 2,6 r„ = 0,75 z'/;'. 



Just as for y =r 0,9 we see also clearly in the above table, that 

 the greateM cluiiuje of h loi/I J)f. in the nehjiihourhood of the critical 

 {or pseudo-critical) point ; hence the coinparatixely large values of 

 h'l: and J)"k, through which r = vk : />/, is reduced from the ideal 

 value 3 to a much lower value, e.g. 2,1 (for y^ = 0,9) or 2,33 (for 

 y)t = 0,75). We may say that the curve h =: f\o) at the beginning 

 and at the end runs almost rectilinearly (at the beginning, between 

 V =: 00 and v = somewhat ^ vi-, parallel to the v-ax\%), while in the 

 part somewhat before and somewhat i)as( Vk the change of direction 

 takes place from to the final direction given by .r„ (above resp. 

 0,39 and 0,26).
