I wrote this program for my own use using Microsoft Visual Basic, but I am releasing it to the public as shareware. I hope others may find it as useful.

Pipe Flow e-Handbook is one of the e-Handbook series of programs released by lales. The e-Handbook program is designed to replace the old, thick and heavy paper handbook, where one usually needs to read the results from tables, charts or monographs. With e-Handbook, one no longer needs to carry the big and heavy handbook around; in addition, just key in the variables and e-Handbook will compute the answers immediately. No need to read from tables, graphs or monographs and try to interpolate values, if there is no exact match. Besides, the e-Handbook program is able to work with different mix of units, such as flow in Mld, head loss in  feet, velocity in m/sec, etc.

e-Handbook has the following advantages over the paper handbook.
