second. JV in equation [3] must be brought over to the 
other side so that it runs— 
ns ee = w(d') [4] 
d, d', d" ... are trial values for d, which are substituted .

log. s 0°16406 
s = 1°459 
For the first trial value for d, take 0°02. Then 
s—d = 1°459 — 0'020 = 1°489. 
It is now necessary to find v corresponding to this new 
pressure s—d. 
Again from (1] Ur (at press. s) =S X 29 
hence v*(at s—d) = (s—d) x 2g 
s—d = 1°439 = log. 0°15806
