What is expansion of liquid?
expansion of liquids
What is the increase of the volume of a substance by the increase of temperature called?
This increase of volume is called expansion
What is water expansion?
temperaturewater's most density: 4 degrees Celsius ( = lowest expansion rate)
What is the expansion of power?
Expansion of tanθ in power of θ
Air expansion and contraction?
expansion is when the air is HOT !
Why is a throttling valve called an expansion valve?
It is not.. A globe , needle , ball valve are used for throttling For expansion either a shock absorber , diaphragm tank or air chamber are used to allow for expansion
What is the difference between a capillary tube and a expansion valve?
The throttling devise can be the valve or the copper tubing that allows the flow of the refrigerant through very small opening also called as the orifice. The throttling devices allow restricted flow of the refrigerant. The throttling devices are also called as the expansion valves because when the refrigerant passes through them the pressure of the refrigerant drops down or it expands..Capillary tube is one of the most commonly used throttling devices in the refrigeration and the air conditioning systems. The capillary tube is a copper tube of very small internal diameter. It is of very long length and it is coiled to several turns so that it would occupy less space. The internal diameter of the capillary tube used for the refrigeration and air conditioning applications varies from 0.5 to 2.28 mm (0.020 to 0.09 inches). Capillary tube used as the throttling device in the domestic refrigerators, deep freezers, water coolers and air conditioners.
What are the Advantages of throttling calorimeter?
An instrument utilizing the principle of constant enthalpy expansion for the measurement of the moisture content of steam; steam drawn from a steam pipe through sampling nozzles enters the calorimeter through a throttling orifice and moves into a well-insulated expansion chamber in which its temperature is measured. Also known as steam calorimeter.
Is gate valve used for throttling?
Never. Throttling will erode the valve seat and then the valve will never shut off completely.
Explain the main difference between overclocking and throttling?
Overclocking is the process of running components past their specified rates. Throttling is the process of reducing the rate at which the component runs. Throttling is often included in the design specs of a processor, so there is usually no danger in it. When you run components below the rate that they are rated for (even for throttling limits), this is generally known as underclocking.
Is pressure after throttling is more or less?
You cannot increase steam pressure through a valve without adding heat to it. Throttling steam always reduces its pressure.
A throttling calorimeter is used to measure the quality of?
steam
Why temp drops during throttling?
Throttling is the process of passing gas through a narrow opening at a high velocity. While doing so the gas expands thereby providing a cooling effect.
What valve is the preferred valve to use in throttling a gate valve or globe valve?
Never ever use a Gate type of valve for throttling ONLY a globe pattern is designed for this purpose and a needle valve
What is a definition for CPU throttling?
the ability to modify CPU clock speed as needed
How you control a gas turbine?
By throttling the amount of fuel delivered to the combustion chamber
What valve types are used for throttling flow?
Ball-joint shut off
