Its simply watering the playing area of the ground - This is very important as the game involves many incidents of players hitting the ground and having to "dig in" to push in rucks and scrums etc. A hard ground would see considerable injury stats

If a building sprinkler system has a sprinkler head of 50 years old is it still good?
It depends. NFPA states that sprinklers over 50 years of age should be replaced or should have a representative sample tested. This means that sprinkler samples need to be pulled from the system and sent to a testing laboratory (UL) for testing. If the sprinkers pass this test, a certificate is issued stating that the sprinklers are still operational.

The process of supplying water by artificial means is called irrigation.
What causes a lawn sprinkler to rotate?
The water accelerates as it moves through the pipe towards the nozzle, newton's 2nd law F=ma means that this water produces a force, newton's 3rd law then states every force produces an equal and opposite force. As this water produces a force, an equal and opposite force is produced. A force acts on the sprinkler opposite to the flow of motion of the water. This causes a torque, T=FR on the sprinkler causing it to spin. Where F is the force produced and R is the distance of the sprinkler arm. The sprinkler does not require electricity to move
What is meant by a mandatory field?
a mandatory field in a database is one created in a table as "Not null". This means, there is a "rule" on the field that when data is inserted into the table, this field cannot be empty. If it is, then the insert errors. Here's part of a table definition in my database. These field are are required to be populated when inserting into this table. ATTR_DESC_01 CHAR(2) DEFAULT SYSTEM NOT NULL, ATTR_DESC_02 CHAR(2) DEFAULT SYSTEM NOT NULL, ATTR_DESC_03 CHAR(2) DEFAULT SYSTEM NOT NULL, ATTR_DESC_04 CHAR(2) DEFAULT SYSTEM NOT NULL, ATTR_DESC_05 CHAR(2) DEFAULT SYSTEM NOT NULL, ATTR_DESC_06 CHAR(2) DEFAULT SYSTEM NOT NULL, ATTR_DESC_07 CHAR(2) DEFAULT SYSTEM NOT NULL, ATTR_DESC_08 CHAR(2) DEFAULT SYSTEM NOT NULL, ATTR_DESC_09 CHAR(2) DEFAULT SYSTEM NOT NULL, ATTR_DESC_10 CHAR(2) DEFAULT SYSTEM NOT NULL, PARTITION_NBR SMALLINT NO DEFAULT NOT NULL)
How does a sprinkler system work as an open loop system?
What you may be referring to, since the question was posted in electrical engineering section, is in reference to the electrical switches and devices installed on sprinkler systems. The systems have water flow devices, low air switches, valve tamper devices and the like. each device is designed to monitor changes in state in the system. (sprinkler waterflow, low air pressure in a system, an improperly open or closed valve, to name a few.) these devices are designed to send an electrical current or signal of high or low voltage to a device(bell or siren) or to an alarm or control panel. The terminals on these devices are similar. They have a "common" terminal. Next, they have an "normally open" terminal; which means the circuit is open normally, but closes during a change in state. The circuit is supervised with a end of line resistor in the circuit, hence an "open loop"

Advice For Homeowners Designing A Sprinkler System?
Sprinkler system design is an area that can become very complex very quickly. A large system requires a person to perform complex mathematical calculations while also accounting for the water needs of different plants and the layout of the property. Some professionals specialize exclusively in sprinkler system design for this reason. Homeowners can take several steps to help plan a workable and functional design for a lawn or yard. Every sprinkler system design should start with a detailed and accurate map of the property. It should include the house, fences and major plantings like trees or raised beds. The map should also include noticeable changes in elevation throughout the property. The next step is to use a template, compass or other guide to start plotting where each sprinkler head will be located. Overlap between the heads should be minimal. Similarly, the range of each sprinkler head should not extend beyond the property by a large amount. It is important to avoid placing sprinklers too close to the house where they can cause water and foundation damage. The next step will determine what components are necessary as part of the sprinkler system design. The two primary numbers that must be measured from an outdoor water source are pounds per square inch (PSI) of pressure and the gallons per minute (GPM). There are several small and inexpensive devices to measure PSI and GPM. Some municipal water services will also run a test and provide the information. GPM is used to determine the flow rate of the sprinkler system and the potential number of heads that can be used. The PSI determines how far the water will travel as well as the types of heads that can be used. Homes with well systems or homes on large properties will likely need a water pump to boost the PSI so that water can work through all the pipes and up inclines. The next step should be to start designing small circuit blocks of plumbing. This means plotting how valves, sprinklers, pipes and other fittings will fit together in just a small area. Planning several of these in sequence will make the sprinkler system design more manageable. One of the final steps should be to consult with a professional for advice before installing the system. Any number of minor issues could cause the system to fail. Professionals will see any problems quickly and can suggest fixes. Additionally, professionals will have knowledge of any local building codes or regulations that the system must meet.
Why is the earth part of the solar system?
When Earth was created, it was sucked into the Sun's gravitational field like the other 7 planets. That is why it revolves around the Sun.
