“Pumping and Hydraulics’ Solutions for Irrigation and Water Supply”
Weeks 4,5,6a: PUMPING
Of all of the Limits of Operation, Net Positive Suction Head is the least understood concept in pumping. This course clearly demonstrates NPSHR (required) and NPSHA (Available)

Many attendees expressed the "WOW" factor from this presentation, with the light suddenly being switched on after decades of mis- understanding the whole NPSH concept!

Attendees are given an Excel program developed by Tallemenco to calculate the suction limits of operation of a pump given its NPSHR, altitude, water temperature and suction pipework configuration.
NPSH limits  the operation of pumps, and therefore energy efficiency.       Graph: R Welke
Capitalised cost of power is a Limit of Operation that has a significant bearing on  system total costs       Graph: R Welke
Did you know that a pump and a cricket bat have something very much in common? Watch the video in this training course and find out what it is!
This module covers the following issues:
Teaser:
Attendees are also given Excel software (also developed by Tallemenco) which calculates where on a curve a pump will operate given its H-Q curve, pumping main length, diameter and C Values.
Other software enables pump duties to be altered with changes in pump impeller diameter and pump speed. It also incorporates Upper and Lower operating duties to determine the pump limits of operation.

Irrigation systems, regardless of type, require a balance between economy of construction, water and energy efficiency.
"Advanced Pumping & Hydraulics" course  teaches the difference.
This course has been accredited by Irrigation Australia for PROFESSIONAL DEVELOPMENT.
Week 6b:
