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.
What is irrigating?
The process of supplying water by artificial means is called irrigation.
What is the relationship between the electric field in a capacitor and the amount of stored energy in the system?
The electric field in a capacitor is directly proportional to the amount of stored energy in the system. This means that as the electric field increases, the amount of stored energy in the capacitor also increases.
What is the relationship between voltage and the electric field in a given system?
In a given system, the relationship between voltage and the electric field is that the electric field is directly proportional to the voltage. This means that as the voltage increases, the electric field strength also increases. Conversely, if the voltage decreases, the electric field strength will also decrease.
Is magnetic field conservative field?
Yes, a magnetic field is a conservative field. This means that the work done by a magnetic field around a closed path is zero, indicating that the energy is conserved in the system.
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"
