How can you measure the diameter of capillary tube by using vernier caliper in traveling microscope?
To measure the diameter of a capillary tube using a traveling microscope and vernier caliper, place the capillary tube on a flat surface. View the capillary tube through the traveling microscope to measure the external diameter. Then, use the vernier caliper to measure the internal diameter by gently inserting the capillary tube between the jaws of the caliper to get an accurate measurement. Subsequently, calculate the average diameter using the two measurements.
What name is given to a tube of very small diameter?
capillary
What is the tendency of a liquid to rise in a small diameter tube called?
The 'capillary effect'. See the link.
How high can water rise in a capillary tube 30 micrometers in diameter?
4.6
Why is a capillary tube thought of as a dry-type?
The Capillary tube metering device is used primarily on small fractional-horsepower refrigeration systems that have relatively constant evaporator heat loads. These systems are hermetically sealed, leak free systems with dry-type evaporators that use a minimum of refrigerant. The capillary tube metering device is a fixed bore device, itcontrols refrigerant flow by pressure drop.
The height of a liquid in a capillary tube is not dependent on?
the height of a capillary tube is not dependent on
Why do liquid rise of fall in a capillary tube?
It is because of the surface tension between liquid molecules and the inner surface of the tube. The meniscus height is determined by the inner diameter of the tube. The smaller the diameter, the higher the meniscus will climb due to capillary action.
Why mercury falls in capillary tube?
Mercury falls in a capillary tube due to the combination of capillary action and gravity. Capillary action is the tendency of a liquid to be drawn up into a narrow tube against the force of gravity. When the adhesive forces between the mercury and the walls of the capillary tube are greater than the cohesive forces within the mercury, the mercury will move downward in the tube.
Why is capillary tube fixed in Ostwalds viscometer?
The capillary tube is fixed in the Ostwalds viscometer is for passing the liquid.
How high can water rise in a capillary tube that is 0.1 millimeters in diameter?
The height to which water can rise in a capillary tube is calculated using the equation h = 2γcos(θ)/ρgr, where γ is the surface tension of water, θ is the contact angle, ρ is the density of water, g is the acceleration due to gravity, and r is the radius of the tube. For a tube with a diameter of 0.1 mm, the radius would be 0.05 mm. Water typically has a contact angle close to 0, resulting in a high degree of wetting, allowing it to rise several millimeters in a capillary tube of this size.
Explain the capillary tube type refrigerant control?
capillary tube are classified under fixed oriffes metering device it is thin and long inorder to control the refrigerant pressure and temperature not to evaporate ontheir way unitl it reach the evaporator.
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.
