Table 3 : Examples for Iceland and Denmark
Putting A ~ H
one has D3/4.H 5/4 = constant
(21)
and for H - d 1/3
one has D 3/4'. d 5/16 = constant
(22)
Similarly for H = d ~/4, one has D 3/4 • d 5/16 =cons tan t
(23)
Using the two assumptions one arrives at the d/D ratios given in table 4 •
H ~- d 1/3 " d->D
2d--,D = 0.7
3d-,D = 0.5
4d-,D = 0.4
H -= d 1/4" d--,D
2d --, D = 0.75
3d --, D = 0.6
4d--,D = 0.5
