Calculator Design Series #2
While reviewing my library for HP65 Programmable Calculator material(s), I ‘rediscovered’ Calculator Design Series #2, Hydraulic Design of Improved Inlets for Culverts using programmable calculators HP65 (1980 OCT) 147 pages. The publication includes 20 programs with examples, equations, limitations etc. An extract from the INTRODUCTION …
The programmable calculator as a culvert designing tool offers many desirable features. Compared with the hand method, the calculator is more accurate, less time consuming, and eliminates all searching through charts and nomographs. In one quarter of the time it takes to design one culverts by hand, the designer could use the calculator to design the culvert, checking four or five different sizes to find the best one, while also evaluating several inlet configurations including both side and slopetapered inlets. My efforts to locate a web repository are ineffective, so I intend to scan and submit the publication for inclusion in the museum document sets (flash driveCDarchives): until then, any requests to post one of the twenty programs to the forums HP65/67/97 Software Library?

This topic reminded me of an old thread: MANPIP
And indeed we find on page 39: Quote:This depth may be determined by trial and error using a form of Manning's Equation:

RE: Calculator Design Series #2
OK; the post belongs in the HP65 software thread, & then eventually in Calculator Literature URL? Since my original post was in this thread & didn't have a link to the HP65 program listings, descriptions, etc., I provided a link, as promised.
