15.5 Use of tables
15.5.1 Nozzle selection
Example:
You have the following data:
- desired consumption per hectare of 400 l
- working speed: 6 km/h
----------------------------------------------------------------------------------------------------------------
1. In the speed column for 6 km/h of table 2 find the desired consumption per hectare 400 l/ha.
2. See the flow rate of the nozzle on the left side of the table; in our case, this is 2,00 l/min.
3. Select the appropriate nozzle at specific pressure from table 1: e.g. TABLE 1, nozzle LECHLER,
brown colour at a pressure of 3.2 bar.
15.5.2 Selecting appropriate speed and working pressure
Example:
- desired consumption per hectare 400 l/ha
- installed LECHLER nozzle, RED colour
- desired pressure between 2 and 4 bar
- desired working speed between 4 and 6 km/h
----------------------------------------------------------------------------------------------------------------
1. In table 1, find the nozzles, installed in your sprayer. LECHLER RED nozzles have a flow rate of
1.26 l/min at a pressure of 2 bar and a flow rate of 1.8 l/min at a pressure of 4 bar.
2. Find the consumption value of 400 l/ha at a nozzle flow rate between 1.2 and 1.8 l/min in table 2;
find the speeds 4-6 km/h in the vertical column. Results:
- 4,5 km/h at a pressure of 2.8 bar
- 4,8 km/h at a pressure of 3.2 bar...
15.6 Different calculations
- The water consumption values can be taken from the tables or calculated in accordance with
the following equation:
𝑾𝑨𝑻𝑬𝑹 𝑪𝑶𝑵𝑺𝑼𝑴𝑷𝑻𝑰𝑶𝑵 𝑷𝑬𝑹 𝑯𝑬𝑪𝑻𝑨𝑹𝑬 [𝒍 𝒉𝒂
⁄
] =
𝟔𝟎𝟎𝒙 𝑵𝑶𝒁𝒁𝑳𝑬 𝑭𝑳𝑶𝑾 𝑹𝑨𝑻𝑬 [𝒍 𝒎𝒊𝒏 ⁄ ]
𝑾𝑶𝑹𝑲𝑰𝑵𝑮 𝑺𝑷𝑬𝑬𝑫 [𝒌𝒎 𝒉 ⁄ ] × 𝑫𝑰𝑺𝑻𝑨𝑵𝑪𝑬 𝑩𝑬𝑻𝑾𝑬𝑬𝑵 𝑵𝑶𝒁𝒁𝑳𝑬𝑺 [𝒎]
- The required flow rate of a nozzle per hectare and the working speed can be calculated with
the help of the following equation:
𝑵𝑶𝒁𝒁𝑳𝑬 𝑭𝑳𝑶𝑾 𝑹𝑨𝑻𝑬 [𝒍 𝒎𝒊𝒏 ⁄ ] =
𝑾𝑨𝑻𝑬𝑹 𝑪𝑶𝑵𝑺𝑼𝑴𝑷𝑻𝑰𝑶𝑵 𝑷𝑬𝑹 𝑯𝑬𝑪𝑻𝑨𝑹𝑬 [𝒍 𝒉𝒂 ⁄ ] × 𝑾𝑶𝑹𝑲𝑰𝑵𝑮 𝑺𝑷𝑬𝑬𝑫 [𝒌𝒎 𝒉 ⁄ ]
𝟔𝟎𝟎
-
The simplest way to determine the tractor’s speed is to measure a certain distance and the
required time to pass this distance:
𝑾𝑶𝑹𝑲𝑰𝑵𝑮 𝑺𝑷𝑬𝑬𝑫[𝒌𝒎 𝒉 ⁄ ] =
𝑫𝑰𝑺𝑻𝑨𝑵𝑪𝑬 𝑻𝑹𝑨𝑽𝑬𝑳𝑬𝑫 [𝒎]×𝟑,𝟔
𝑫𝑹𝑰𝑽𝑰𝑵𝑮 𝑻𝑰𝑴𝑬 [𝒔]
WARNING: Check the actual flow rate of the nozzles by measuring it. If the flow rate of
a nozzle at a specific pressure exceeds the table values for more than 10%, then the
nozzle insert is worn and needs to be replaced .
