PIPECALC VERSION 1.0
--------------------

Pipecalc is a program for the Psion 3A which calculates data for pipes of a circular section. It is based on the Colebrooke-White method which is in common use in the United Kingdom. 

Pipecalc can be used to calculate flow in a circular section of known size or to calculate a pipe diameter for a known flow. The program also shows the capacity, spare capacity and self cleansing velocity (which can be changed from the default 0.76m/s) and relationship of surface roughness to 15mm as a simple graphical bar for ease of use.

Although Pipecalc is supplied as free to use software, I'd appreciate your registering it with me. So, after you've used it a couple of times, please fill out the form in the registration section below and e-mail it to me at 101735.3054@compuserve.com
