PIPEDATA V2.01 PROGRAM DESCRIPTION
for the IBM PC/XT/AT and compatibles
PIPEDATA V2.01 is a powerful tool that engineers and
technical people need everyday to calculate the
characteristics of liquids and gases that are being
transported through pipe and tubing sections. The program
calculates the velocity of the fluid, the Reynolds number,
the friction factor, and the pressure drop due to fluid
resistance with any pipe material. Darcy equation is used.
The program allows the user to enter data into the computer
using a simple, yet elegant, data editor for defining problem
variables; such as fluid density, fluid viscosity, fluid flow
rate, pipe material roughness, pipe material internal
diameter, and pipe section lenght. The editor allows the
user also to compare the effects caused by the change in any
variable, and re-calculating the results quickly and easily.
This is great for analyzing "What If?" situations.
Besides being a computational tool, PIPEDATA provides
schedule and dimensional information on nominal pipe sizes
from 1/8 through 36 inches. This data is extracted from ANSI
B36.1 and ANSI B36.19. Pipe property data is also
calculated; such as: wall thickness, metal area, moment of
inertia, weight of water filled pipe, weight of steel pipe,
and pipe section modulus. The database is flexible to use,
and appears as a program help window. Since the majority of
the type of fluid flow problems encountered by most of the
engineering disciplines deals with water as the fluid medium,
the program has these variable properties initially preset to
model those of water at 60 degrees Fahrenheit, and flowing
through clean commercial steel pipe. These all can be
changed to whatever you need. To calculate using the preset
variables, you only need to define the fluid flow rate, and
the internal diameter of the pipe, then pressing the C key,
the program will provide the results within approximately
one-half second. The program uses state of the art formulas
for calculating the friction factor without iteration, or
having to define a convergence criterion. The flow may be
laminar, or turbulent, and applicable within the limitations
of the Darcy equation formula.
The main screen layout for the program is simple and
straightforward, it consists of an input column, and a
results column. A computer color monitor is recommended in
order to appreciate the programmed screen colors. If your
computer has a clock, the correct date will appear on the
upper right part of the screen. This feature is useful for
when preserving a calculation copy on paper. To print any
calculation results, simply turn on your printer and when
ready press your PrtSc key on your keyboard. Whatever is on
your screen will then be printed onto paper. Some graphics
characters are possible on some printers.

TO RUN THE PROGRAM, after booting up your DOS, simply place
the program diskette in your A drive and type "PIPEDATA"
followed by pressing the Enter key. The program will
initialize to the Copyright screen. Press any key to get to
the main screen. If you need Help in using the program press
your H key, and a menu will appear. If you wish, play around
with the program, compare your answers with those found in
water flow tables, such as found in Crane Technical Paper 410
Appendix B-14. Change values for the input variables, then
press your C key to compute your results. These instructions
are all found within the program help menu, and help screens.
This program does not need detailed documentation, but it
may be provided at a later date, on diskette (ready to be
printed onto any ASCII printer), or provided separately.
