Ship Squatting Problem: Bivariate Plot


Barrass [1]: S =1/30 · Cb · (As / [Ac - As] )2/3 · Vk2.08
Millward [3]: S =(L/100) · ([15 · Cb · (B/L) - 0.55] · Fnh2 ) / (1 - 0.9 · Fnh )
Norrbin [4]: S =(L/100) · ([100 / (L/h)] · [As / Ac] · Fnh2 ) /
(1 - [As / Ac] - [(h · W0) / Ac] · Fnh2 )
Tuck [5]: S =L · Cs · Fnh2 / (1 - Fnh2 )1/2

Clearance:c =h - T - S

Plot the contours f(X,Y) = ct for (select 1)
Independent variables: X is: ranging from: to:
Y is: ranging from: to:

Specify the constant parameter values (ignoring the independent variable fields):
Ac: (BN) As: (BN) B: (M)
Cb: (M) Cs: (T) h: (BC)
L: (MN) T: (BC) Wo: (N)

and either Fnh or V: (MNT or B)
where the letters in parentheses indicate which formula requires that parameter (B = Barrass, etc.).
