I hope you have seen people spraying in the farms; they use electrical or fossil fuel sprayer to spray pesticides on the field. Today, we will talk about alternatives such as mechanical sprayer.
What is mechanical sprayer?
We discussed Pascal law in our post Hydraulic Car lift. We would use same concept here. Mechanical Sprayer consists of small cart, drum, pipe and sprayer itself. It works like a steam engine but in exactly opposite way. Here, when we move cart forward, wheels of cart revolves and push piston in downwards direction. This downward motion of piston push pressure on water and as a result it comes out from the sprayer.
