Theory Compresed Gasses Flashcards
What is Pascal’s Law?
A principle stating that pressure applied to a confined fluid is transmitted undiminished in all directions.
This law is foundational in fluid mechanics and is used in hydraulic systems.
What does Boyle’s Law describe?
The relationship between the pressure and volume of a gas at constant temperature.
It states that the pressure of a gas increases as its volume decreases.
What is Charles’s Law?
The principle that the volume of a gas is directly proportional to its temperature at constant pressure.
This law indicates that when the temperature rises, the gas expands.
What is Torricelli’s Principle?
A principle that describes the speed of fluid flowing out of an orifice under the force of gravity.
It is often applied in fluid dynamics.
What are vacuum and pressure scales used for?
To measure the pressure of gases and liquids, including vacuum conditions.
These scales help in various scientific and industrial applications.
What are common temperature scales?
- Celsius
- Fahrenheit
- Kelvin
Each scale has its own application and conversion methods.
What is atmospheric pressure?
The pressure exerted by the weight of the atmosphere above a given point.
It is typically measured in pascals (Pa) or atmospheres (atm).
What is the heat of compression?
The increase in temperature of a gas when it is compressed.
This phenomenon is important in thermodynamics and gas compression processes.
What does flow rate refer to?
The volume of fluid that passes a point in a system per unit of time.
It is typically measured in liters per second (L/s) or gallons per minute (GPM).
What is energy transmission?
The process of transferring energy from one location to another.
This can occur in various forms, including heat, electricity, and mechanical energy.
What is heat energy?
The energy that comes from the temperature of matter.
It is often associated with the kinetic energy of particles.
What is pressure energy?
The energy stored in a fluid due to its pressure.
This energy can be converted into kinetic energy when the fluid is allowed to expand.
What is air compression?
The process of reducing the volume of air, increasing its pressure.
This is commonly used in various engineering applications.
What does adiabatic mean?
A process in which no heat is exchanged with the surroundings.
Adiabatic processes are important in thermodynamics.
What does isothermal mean?
A process that occurs at a constant temperature.
This is often used in the context of gas laws.
What are gas laws?
The laws that describe the behavior of gases in relation to pressure, volume, and temperature.
These include Boyle’s Law, Charles’s Law, and others.
What is compressor operation?
The process of increasing the pressure of a gas by reducing its volume.
Compressors are widely used in various applications, including refrigeration and air conditioning.
What is a compression ratio?
The ratio of the volume of a gas before compression to the volume after compression.
This metric is crucial in engine design and performance.
What does negative pressure mean?
A condition where the pressure is lower than atmospheric pressure.
Negative pressure can have various applications, including in vacuum systems.
What is atmospheric pressure measured in?
- Pascals (Pa)
- Atmospheres (atm)
- Millimeters of mercury (mmHg)
These units are used in various scientific and engineering contexts.
What is the significance of laws and principles in science?
They provide foundational understanding and predictability of natural phenomena.
Laws and principles are essential for scientific inquiry and practical applications.
