AUTOMATIC GARDEN WATERING PLANTS
AUTOMATIC GARDEN WATERING
About the automatic watering of the garden there are mainly two types of automatic :
A) Drip irrigation and
B) watering with sprinklers (lawn)
In this article I will refer only to the first category.
Drip irrigation is used for watering trees, shrubs and more
plantlets. For watering the use tubes with integrated drip distances that we want for ourselves or put their emitters to a similar benefit. Water flow can have either water supply or pump. To do proper calculations
measure the static pressure and supply network at various pressures with flow meter (flow meter for the mention details on automatic watering patio). Unless we use a flow meter valve with pressure gauge and a specific container capacity. Open the valve in different positions and timers filling the container. In this way we have been providing the network at various pressures.Eg opening the valve so that the manometer writes 2bar and the container fills 10 liters in 20 seconds, then the provision in 2bar is 10/20 x 3600 = 1800litra per hour. Depending on the measurements and draw conclusions about the pressure of the network and the number of solenoid will need to ensure watering of all plants. Though our garden is small
you will not need to go into too much trouble and ypologismous.Me a programmer remove the work as long as you make sure that the pressure exerted by the network scheduler is not above the permissible limits.

But if the garden is large with several longitudinal fences should go into special studies.
A factor we should take into account the friction of the pipe. The chart below shows pressure losses polyethylene tube as the outer diameter (and thickness) example : 20mm tube (external diameter on the 20th mm) and a wall thickness of 2 mm, when water is 0.2 liters per second (= 0.2ch3600 720 liters per hour) has lost pressure 0.9 Bar to 100meters (the 1st Bar = 100 kPa)
The velocity of the water in this pipe is :
Provision / 1000 p R on the 2nd 0.2/1000x3.14 = x [0.020-2 (0.002)] the 2nd =
0.2/3140x0.016 = two = o.2/0.8 = 0.25m/sec
Another factor is how many drip has built and how much benefit everyone .
Eg if you have a pipe 100 m drip ana33 cm 2 supply L / h then the total flow tube is 600 L / h.
below The small boards helps us to understand the maximum pipe lengths that you can use with differential first-last dripper 15% in water supply, whereby the inlet pressure during flow (not static) is 1bar. Below this there is the diagram of each emitter showing the relationship of pressure-flow rate.

Another factor is whether our surface is flat, uphill or downhill. The ten m uphill deprive us 1 Bar pressure. It is advisable in such cases to use aftorithmizomenous drip.
Play an important role and the possibilities for providing solenoid. The instructions inform us the maximum performance of the valve
And the latter factor is whether we seasonal pressure drops in the network or fall pump performance over time.
Offsetting all the above factors make our study.
If we do not do so good with math and makes it difficult to study, we can apply the experimental pipes!
20mm: 1100 liters / hour
F25: 1800 liters / hour
F32: 3050 liters / hour
F40: 5400 liters / hour
F50: 8400 liters / hour
(These benefits are calculated 4atm pressure to the water source ( faucet).
4atm The pressure is the average pressure in the water mains.)
Finally if the garden will need more than a solenoid instead programmer battery integral with the solenoid, you will use main power programmer, severed from the solenoid, with 2,3,4,5,6 etc stops for more convenience and control of watering.

Its looks good but it needs more clarifications. Thank you for your post. Please visit my post
