Q: In a viscometer, what does the time taken for a fluid to flow through a capillary tube indicate?
Solution: The time taken for a fluid to flow through a capillary tube is directly related to its viscosity.
Steps: 7
Step 1: Understand what a viscometer is. A viscometer is a device used to measure the viscosity of a fluid.
Step 2: Know what viscosity means. Viscosity is a measure of how thick or sticky a fluid is.
Step 3: Learn about the capillary tube. A capillary tube is a very thin tube through which the fluid flows.
Step 4: Observe the process. When a fluid is poured into the viscometer, it flows through the capillary tube.
Step 5: Measure the time. The time it takes for the fluid to flow through the tube is recorded.
Step 6: Relate time to viscosity. If the fluid takes a longer time to flow, it means the fluid is more viscous (thicker). If it flows quickly, it is less viscous (thinner).
Step 7: Conclusion. Therefore, the time taken for a fluid to flow through the capillary tube indicates its viscosity.
