Need Help to Select The Right Solar Pump?

Step 1:  Work out how much water you need per day

Here's a table showing the base water needs of livestock.  Please note the figures are estimates only and will vary from area to area throughout Australia

SHEEP

SUMMER

WINTER

 

CATTLE

SUMMER

WINTER

Lactating Sheep

9L

7L

 

Grazing  over 550 kg

66L

45L

Dry Sheep

7L

4.5L

 

Lot Feeding

91L

60L

Irrigated Sheep

3.5L

2L

 

Calves

25L

15L

       

Dry Cows

45L

30L

 

Step 2:  Work out the total dynamic head the pump needs to deliver against:

 

 

 

Please referring to the diagram to the right:

Total dynamic head is the total of:

  • Vertical lift
  • Friction losses in the pipe between the pump and the destination.  You can calculate friction losses here or refer to the table below.

PIPE FRICTION LOSS

In this example, calculate the total friction loss in a pipeline. Enter the flow rate, internal pipe diameter, and the type of pipe from the list supplied. Leave pipe length as 100 to get the friction loss per 100 m/ft of pipeline.
