Introduction to Thermodynamics Part 3 Flashcards
no mass transfer and energy transfer
isolated system
In an equilibrium state, there are no ________________________ within the system
unbalanced potentials
the real or imaginary surface that separates the system from its surroundings
boundary
Some manometers use a slanted or inclined tube in order to increase the resolution (precision) when reading the fluid height. Such devices are called?
inclined manometers
It usually encloses a device that involves mass flow such as a compressor, turbine, or nozzle
open system or a control volume
this implies a state of balance
equilibrium
system where energy can both go in and out
closed system
system where energy and mass can both go in and out
open system
the system involves no temperature differential, which is the driving force for heat flow
thermal equilibrium
any point at which all the thermodynamic properties of a system can be known
thermodynamic state
unbalanced potentials other term
driving forces
is the measure of the amount of force acting on a mass due to the acceleration due to gravity
weight (W)
the temperature is the same throughout the entire system
thermal equilibrium
The boundaries of a control volume can be?
real or imaginary
the driving force for heat flow
temperature differential
the mass of each phase reaches an equilibrium level and stays there
phase equilibrium
chemical composition does not change with time, that is, no chemical reactions occur
chemical equilibrium
The boundaries of a control volume or open system are called a
control surface
defined as a quantity of matter or a region in space chosen for study
system
4 types of equilibrium
Thermal
Mechanical
Phase
Chemical
a properly selected region in space
open system or a control volume
A control volume can involve these boundaries
fixed, moving, real, and imaginary
is usually considered to be one of
the primary dimensions and is assigned a nonderived unit
force
there is no change in pressure at any point of the system with time
mechanical equilibrium
the initial and final state is the same
thermodynamic cycle
any change that a system undergoes from one state to another state
thermodynamic process
the mass or region outside the system
surroundings
other term for open system
control volume
