DIAMETER-IN? : tank diameter (2R)
SLOPE HT-IN? : height of sloped part (h0)
CYLINDER HT? : height of cylinder part (d)
HATCH HT-IN? : height of dome above cylinder (v0)??
HATCH DEPTH : height from bottom of hatch to top of dome?
JUICE LEVEL : Height from top of dome to top of juice level.

The math at the beginning, the flowchart and the program seem not to be consistent. You're not the only one who is confused. ;-)

According to fig. 25-5 Vo is the height of the dome top, not the hatch height. "hatch ht" and "hatch depth" seem to define the position of the hedge (as stated in the text above the program listing). The formulas and the flowchart consider the dome radius R, but the program does not prompt for it.

You can determine R from Vo and r, cf. my last post above. But I don't think this formula is mentioned anywhere in the PDF.

As already pointed out the given data in table 25-3 are inconsistent. You can assume a certain R and calculate Vo from this (cf. Geoff's post), or you may assume that Vo is given and calculate the corresponding R. Which is s what I chose as I think that Vo can be easily measured while determining R graphically is more cumbersome and error prone.

The HP67 program I wrote allows to override the calculated radius. For the example in table 25-3 the radius R is calculated as 90" which gives 13318 and 13509 gallons. Overriding the calculated R with R=78" gives the same results as the PDF, i.e. 13284,4 and 13444,4 gallons.

So I'd recommend you write your own program. This way at least you know what to enter and what results you get. ;-)
