gobar gas plant kaise kaam karta hai hindi me
gobar(cow dung) gas plant is a good example of scientific model with waste material.
Instead of using LPG gas we can use gobar gas to cook
By mixing of fresh cow dung with water and make a slurry then put it into the plant. This preparation is contineous till the tank is filled up. Then wait for 72 hours to produce gas.
