PIPE Elements 5 Flashcards
It is an exhaust gas-driven compressor used to increase the power output of an internal-combustion engine by compressing air that is entering the engine thus increasing the amount of available oxygen.
Turbocharger
The difference between chimney and stack construction
Chimney generally denotes brick concrete construction while stack means steel construction
It is a valve or plate used for controlling draft or flow of the flue gases and may be automatically or manually operated
Damper
A type of fire protection system in which the pipes are not normally filled with water. Water is introduced into the system thru Fire Service connections when needed.
Dry Stand Pipe
Fire involving energized electrical equipment
Class D
Fire involving flammable liquids and gases
Class C
A system employing open sprinklers attached to a piping system connected to a water supply through which is opened by the operation of a fire detection system installed in the same areas as sprinklers.

22.8
A machine which is used to add energy to a fluid in order to transfer them from one point to another point of higher elevation
Pumps
An ideal type of pump used for pumping water with low discharge, high head, low speed, & self- priming.
Reciprocating
The speed at which a geometrically similar impeller of a pump would run to discharge 1 GPM at 1 foot head.
Specific Speed
The tank is an unfired pressure vessel, initially full of air, into which water from mains is pumped.
Hydro-Pneumatic Tank
It exist when the total suction is below atmospheric pressure.
Suction Lift
A soft material that can be shaped and compressed to provide a seal
Packing
A pipe with a thin wall used to carry fluids
Tubing
__________ means maintaining a space cooler than the surrounding
Refrigeration
The temperature at which the water vapor in the air condenses when the air is cooled at constant temperature.
Dew Point
The temperature of air if it is saturated
Wet bulb
Heat transfer from one place to another using a fluid
Convection
The terminal or end device in an air distribution system that directs air in a specific direction
Diffuser
A sealed channel used to convey air from the system to and from the point of utilization
Duct
Pipes carrying steam are generally made up of
