The radius of a capillary tube can vary widely depending on its application and design, but it is typically in the range of a few micrometers to several millimeters. In the context of fluid dynamics, the radius is crucial for understanding capillary action, as smaller radii enhance this phenomenon due to increased surface tension effects. For precise applications, such as in medical devices or laboratory settings, specific dimensions are selected based on the desired flow characteristics.

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.
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.
Why there is capillary action and why the effect is greater for narrower tubes?
Liquid rises in and out of cappilarry to compansate pressure difference. Rise of a liquid in capillary is indirectly proportional to radius of tube so liquid goes higher in a narrow tube.

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.
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 extra precaution required while measuring the radius of the capillary tube?
Extra precaution is required while measuring the radius of a capillary tube because even small inaccuracies can significantly affect the results in experiments involving capillarity, fluid dynamics, or pressure calculations. The radius directly influences the behavior of liquids within the tube, such as flow rate and surface tension effects. Additionally, capillary tubes are often very thin, making precise measurements more challenging and necessitating careful techniques to avoid errors. Accurate measurements are crucial for ensuring the reliability and validity of experimental outcomes.
