Resistance calculation using HOLTROP

[ngyen]

hy

i am trying to write a small program in VB to calculate resistance for ship which follow Holtrop Mennen.
following this paper.

http://www.4shared.com/document/Z-32...Vol29_1982.htm

I want to know the formulae for calculating the following parameter.i searched but cant get any specific formula for this.
In my program , the input is variable and they are ask the user to give ( L, B,T,H,Cb , Speed )

please provide me formula for these

ABT = Transverse sectional area of the bulb at the position where the still water surface intersets the stem = ???

SAPP = the wetted area of the appendages = ??

AT = Transom Area = ??

hB= Centre of bulb area abolve keel line = ???



please help
thanks

These are variables and will differ from ship to ship. There is no one size fits all formula.

Would suggest you have a look at this dissertation. It deals with the preliminary power prediction process and utilises Holtrop and Mennen amongst others.

If my memory serves me correctly, it provides reasonable examples of using the software together with the output.
