What is the throttling process?
What is the throttling process?
Throttling is a process where a high-pressure fluid is converted into low-pressure by using a throttle valve. In a throttling process, the enthalpy remains constant and the work done is zero.
What is throttling process with example?
An example of a throttling process is an ideal gas flowing through a valve in mid position. Because mass flow is constant, the change in specific volume is observed as an increase in gas velocity, and this is verified by our observations.
Which is true about throttling process?
Solution(By Examveda Team) Different gases will have different inversion temperatures usually the hydrogen and helium will have very low maximum inversion temperatures so, cooling by using throttling for these gases is slightly difficult.
Why throttling process is adiabatic?
In thermodynamics energy transfer is either by heat or by work. Since there is no work involved it is essential that there is also no loss or gain of heat , to maintain the isoenthalpic condition of the flow.. Hence throttling (ideal) is adiabatic.
Is a throttling process isothermal?
Throttling of an ideal gas is both isenthalpic and isothermal.
What is throttle in API?
API throttling is the process of limiting the number of API requests a user can make in a certain period. An application programming interface (API) functions as a gateway between a user and a software application.
Why throttling is done?
Complete step by step answer: Throttling process is a thermodynamic process which is used to reduce or decrease the pressure of a fluid. In this process a liquid having high pressure is converted into low pressure fluid. So the process can’t be reversible.
Does temperature change in throttling process?
Suppose an ideal gas is throttled. Since throttling process is isenthalpic, and for an ideal gas enthalpy is a function of temperature only, the temperature of an ideal gas does not change during a throttling process.
Is throttling always isenthalpic?
Since throttling process is isenthalpic, and for an ideal gas enthalpy is a function of temperature only, the temperature of an ideal gas does not change during a throttling process.
Can temperature change in a throttling process?
What is throttling in Web?
Network throttling is an intentional slowing down of internet speed. In web performance, network throttling, or network condition emulation, it is used to emulate low bandwidth conditions experienced by likely a large segment of a site’s target user base.
How do you implement throttle?
You can implement throttling by adding @Throttling annotation to the service method of the request that should be throttled. As you can see @Throttling annotation alone is equivalent to the annotation below with parameters. The default is 1 method call per second.
What is a throttling process?
A throttling process is a thermodynamic process, in which the enthalpy of the gas or medium remains constant (h = const). In fact, the throttling process is one of isenthalpic processes.
How do you reduce the pressure during throttling?
A partially open valve or a porous plug can be used to reduce the pressure in a system. The changes of the temperature during throttling process are subject of the Joule-Thomson effect. At room temperature and normal pressures, all gases except hydrogen and helium cool during gas expansion.
Is adiabatic throttling possible?
Finally, the theory states that an ideal throttling process is adiabatic. This cannot clearly be proven by observation since a “real” throttling process is not ideal and will have some heat transfer.
What is the effect of throttling on Vapor quality?
In this case of the throttling process (1.15MPa to 1MPa) the vapor quality increases from 87% to 87.4% and the temperature decreases from 186°C to 179.9°C. Throttling of wet steam usually causes an increase in vapor quality, increase in entropy and decrease in temperature.
