Pumping systems design Nyangasi 03/14/12 Page 3 of 15 a) Total Static head The total static head (hts) in the pumping system is the water level difference between the suction and delivery reservoirs. Most of these pumps operate within a range of discharge and head where the Chapter 6 Irrigation System Design Part 652 Irrigation Guide (210-vi-NEH 652, IG Amend. For typical systems, it is around 25% of the total. Most of the pump principles presented here apply to any pump use, not just irrigation.) This category includes pumps such as centrifugal pumps, vertical turbine pumps, submersible pumps and jet pumps. Our pump will need to supply this much water at 10-15 psi pressure to the field’s submain. 3. impeller causes and directs movement of the water inside the pump. Morocco. Use the FloJak Slide Calculator to Estimate the Ideal Pump Kit Length for sizing submersible well pumps and jet well pumps. This time we already know the sizes for sections 1-6, they were entered into the spreadsheet when we did the red section. Size Matters! figure out how much head and flow you need from the pump to begin with, and then match that to the curve of standard manufactured pumps to arrive at the best fit. (Not looking for an irrigation pump? As another example, if a drip irrigation system requires 20 psi (138 kPa) from the pump, then this pump can deliver 25.2 gpm (1.59 lps) at this pressure. 4. η = water hp out / hp into pump 0 < η < 1 If the pump in the last example uses 17.0 HP to provide 13.0 WHP, the pump efficiency is: o-rings adapt the various parts of the pump. How submersible pumps work 3. Head Loss due to Elevation difference from the Pump Room to irrigation System = 10.95 m. Head loss due to Pump Room Fittings can be considered as 5.0 m. Maximum Head Loss due to Pipe Fittings (Main line & Lateral lines) can be considered as 3.0 m. Total Head Loss Calculation: As a manufacturer and supplier of centrifugal pumps and positive displacement pumps we offer the optimum for both applications.

This solar system will pump water from the land which means underground water or nearby creek or river and will replace the use of gas powered pumping which is a costly operation for farmers. pumping system for irrigation of Asparagus. Calculate the “weighted catch” by multiplying the volume collected in the catchcan by the position number of that catchcan. The pump size is determined by knowing the pressure required to run the irrigation system properly. Pump size determines well diameter. This is shown in Figure 1 for the two alternative suction arrangements. In addition, information is provided on irrigation systems that are appropriate for 5 acres or less, including pumps, pipelines, and water application options.
