What name is given to a tube of very small diameter?
capillary
Is a capillary a vessel?
where the blood travels from the lungs to left the atria.^^^ This answer is wrong in every salient way. Use the Wikipedia entry here: http://en.wikipedia.org/wiki/Capillary
What is a very small artery that delivers blood to the capillaries?
The blood vessel that only allows one corpuscle to go through at a time is called a capillary.
Very small tube that carrys blood?
Inside the body it would be a Capillary, vein or an artery, Capillary being the smallest
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.
Describe the structure of a thermometer?
The thermometer consists of a very fine glass tube having a very small bore and is called capillary tube. At one end of capillary tube a very thin glass bulb is provided. The bulb is filled with mercury( most of the times) or alcohol The other end of capillary tube is sealed. The capillary tube is protected by a thick glass tube called stem. On the stem are made markings. These markings are called graduations or degrees.
What are the pros and cons of a capillary tube in refrigeration?
Capillary tube is a very simple device and can be manufacture easily at low cost. The capillary tube can limit the maximum amount of refrigerant to be charged eliminating the need for a receiver in the refrigeration system. Another advantage is when the refrigeration plant is stopped, the pressure along the capillary tube and the entire system remains constant which means that if the compressor is restarted it does not need moreÊpower to overcome high pressure in the system. Hence, smaller compressors can be used instead of big, expensive ones. A disadvantage with capillary coil is that this system is non adjustable due to the fact that the control of the flow of pressure is dictated by the inside diameter of the tube.
Why extra precaution required while measuring the radius of capillary tube?
The radius of a capillary tube is a very important measurement and must be taken with extra caution due to the small size of the tube. A small error in the measurement can lead to significant errors in the calculations. The narrow diameter of the tube also means that the measurement is more prone to errors from vibration or air currents, making it more difficult to get an accurate reading. In addition, the radius of the tube is also affected by the surface tension of the liquid it contains, which can cause the tube to deform or become curved. This can lead to incorrect measurements and must be taken into account when measuring the radius of a capillary tube. Finally, measuring the radius of a capillary tube requires special tools and techniques. A micrometer or vernier caliper may be needed to accurately measure the radius, and special care must be taken to ensure that the measurement is taken in the middle of the tube. Additionally, the measurement should be taken multiple times to ensure accuracy as the tube may deform or change shape over time.
What is arterio-venous capillary bed?
The arteriovenous capillary bed is formed when very small arteries come together with very small veins. These very small veins are called venules and the very small arteries are called arterioles. This is where gas exchange occurs between the circulatory system and the cells.
What line on the ac unit is the low side and what is the high side?
The high side of an a/c is as follows: The compressor ,the capillary( the capillary is a very narrow tube with an inside diameter about the size of a pencil point. )The cap tube is factory sweated to the return line from the evaporator to cool it down. As soon as this cap tube reaches the coil of the evaporator, the tube is much larger in diameter. This causes the freon to expand and it changes from a gas to a liquid. It is very cold and starts to attract warmth from the room. You will notice a small frost line which will rapidly melt because the freon used in an a/c boils at a lower temperature than the freon in a refrigerator. This sweating will continue to cover more of the evaporator, which is the low side because the pressure drops. When it reaches the evaporator, as the freon leaves the evaporator, it enters the suction line. It then goes back to the compressor where it is pressurized back through the cap tube again. This cycle is repeated again and again. So on the high side,, you have the compressor and the capillary tube and on the low side the evaporator and the suction line. It sounds complicated, but is really a very simple continuous cycle at a very fast speed.
Describe what a blood capillary look likes?
A very narrow organic flexible tube
What is an orafice tube in an auto air conditioning system?
the orifice tube is the very small capillary gas control tube that meters the gas from the compressed high pressure side of the system to the low pressure side. Some times they will get stopped up either from moisture in the system or from blown screens on the dryer filters.
