What are the advantages and disadvantages of using a capillary tube?
Capillary tubes are used in a variety of applications including medical, thermometers, science, and technology. Advantages of capillary tubes are: 1. They are inexpensive and simple. 2. No maintenance is required because they have no moving parts. 3. In technology, they reduce the starting torque of the motor by providing an open connection between the condenser and the evaporator Disadvantages : 1. They cannot adjust themselves to changing flow conditions 2. They are susceptible to clogging because the bore is so narrow. A filter should be used to prevent entry of particles or moisture. 3. In technology, specially refrigerant and HVAC, flooding of the evaporator may occur and damage to the compressor may result upon start up.
The rise of water in a narrow test tube is called?
The rise around the edges is called the meniscus, like capillary action this is caused by the adhesion of the liquid molecules to the walls of the container. In a large bore tube like a test tube or graduated cylinder this pulls up the edge and creates a concave meniscus, in a smaller bore tube this actually pulls the liquid toward the top of the tube.
What has greatest capillary action?
Water has the greatest capillary action due to its strong hydrogen bonding and cohesive properties, allowing it to easily move through narrow spaces and against gravity. Other liquids with high capillary action include mercury and ethanol.
How would you measure valve guide bore?
Valve guide bore can be measured using a bore gauge. The bore gauge is inserted into the valve guide, and the measurement is taken by expanding the gauge until it makes contact with the inner walls of the guide. The bore diameter can then be read directly from the gauge.
How are bore and stroke given in the metric system?
Bore and stroke are typically given in millimeters in the metric system. Bore refers to the diameter of the cylinder, while stroke refers to the distance the piston moves from top dead center to bottom dead center in the cylinder.
How should you do to increase the accuracy of the thermometer?
using a thin capillary bore using a thick glass stem
Why the capillary tubing has a uniform bore?
As a metering device you need uniformity
What is the bore of a cappillary tube?
The bore of a capillary tube is the inner diameter of the tube, which is very small typically ranging from below 1 millimeter down to a few micrometers. It is designed to facilitate the movement of liquids through the tube using capillary action.
The capillary tubing has a uniform bore in a mercury thermometer?
yes ! to insure linearity
What is a thermometer bore?
A bore refers to the extremely fine or narrow tube found in a thermometer. It is called a narrow bore or a capillary.
How does the size of capillary bore of a thermometer affect its accuracy?
As the temperature rises, the mercury expands into a narrow bore, because the volume of the mercury increases. If the bore is very narrow then the extra volume has to go a longer way up the bore to accomodate that volume, so it is more sensitive to small changes of temperature. And it is easier to spot small changes of temperature, and read them from the scale more accurately. But if the scale isn't marked accurately in the first place you are no better off.

What are the advantages of using re manufactured engines?
one thing is the block has been heated and cooled so muchthat the new bore and crank alignment stays better

What can you use instead of bore oil?
Cork grease. :)
