flow charts
What does start/stop do in a flowchart
it is an oval shape that represents the beginning and the end of a flow chart, start or end is written inside to represent which one is is.
open loop
no feedback used in processes
What is fluid power
A system that transmits and controls energy through the use of pressurized liquid or gas
regarding properties of gas what variable is represented with a (T)
Temperature
what is Boyle's law
The volume of a gas at constant temperature varies inversely with the pressure exerted on it.
what does process do in a flow chart
process is a rectangle shape and represents an action or verb
closed loop
feedback used in the programming to make operational and process decisions (temp, time, analog value, digital value, etc.)
pneumatics
the media used is air
regarding properties of gas what variable is represented with a (p)
pressure
What is Charles law
Volume of gas increases or decreases as the temperature increases or decreases, provided the amount of gas and pressure remain constant.
What does input/output do in a flow chart
input/output is a rhombus shape and it indicates that manual opperation is needed
digital
signals have 2 states: 1 (closed) or 0 (open)
hydroulics
the media used is oil or water
regarding properties of gas what variable is represented with a (V)
volume
What is Gay-Lussac’s law
Absolute pressure of a gas increases or decreases as the temperature increases or decreases, provided the amount of gas and the volume remain constant.
what does decision represent in a flowchart
decision is a diamond shape and the outcome is either yes or no
Analog
data represented continuously with variable quantities
what is a pump or compressor in a fluid system
device used to move fluids
what is gauge pressure
Pressure on a gauge does not account for atmospheric pressure on all sides of the system
What is pascal's law
Pressure exerted by a confined fluid acts undiminished equally in all directions.
What do arrows represent in a flowchart
the arrows indicate which direction the flowchart moves in
What are three examples of analog control systems
(photoresistor, NTC resistor, potentiometer
What is an actuator (Cylinder) in a fluid system
Mechanical device for moving or controlling a mechanism or system
what is absolute pressure
Atmospheric pressure plus gauge pressure
The force per unit area exerted by a fluid against a surface
