| Abstract | ||
| The research was done in the State Company for Mechanical Industries / Iskandariya for the year 2010 – 2011 to study the influence of increase the revolution and delivery head for irrigation pumping unit 100NVA (4"×4") in : discharge , water horse power, brake horse power and pumping unit efficiency . The pump has two speeds which are 1450 RPM and 1950 RPM as well as three points of delivery head 0.5 Bar , 1 Bar and 1.5 Bar . The experiment was done by using (CRD) Complete Randomize Design in three replicates . The results were as follow : Increasing pump speed from 1450 to 1950 RPM has led to significant increase in discharge, WHP ,BHP , significant decrease in pumping unit efficiency and Increasing delivery head has led to significant decrease in discharge and significant increase in WHP, BHP and pumping unit efficiency | ||
