Explanation:

What is a sprinkler system?

A technique for applying irrigation water that mimics natural rainfall is sprinkler irrigation. A system of pipes is used to distribute water, typically via pumping. Sprinklers are used to spray it into the air, where it fragments into tiny water drops that land on the ground. An irrigation sprinkler is a tool used to irrigate (water) agricultural crops, lawns, landscaping, golf courses, and other locations. It is also known as a water sprinkler or just a sprinkler. Buildings with sprinkler systems installed as a preventative precaution can battle fires more effectively.

What is Threshing?

The process of separating the grains from the plants is known as "threshing." These tasks may be completed manually, with the assistance of animals or equipment, in the field or on the threshing floor. Care must be taken when threshing, no matter the system employed.
