How Does Adding a Lighter Liquid Affect Water Displacement in a Modified U-Tube?

In summary, Figure 14-32 shows a modified U-tube with unequal arm lengths and a 1.30 cm radius. Water is added to the left arm until it begins to flow out of the shorter, 10.0 cm high right arm. Then, a liquid with density 0.830 g/cm3 is added to the left arm until it reaches a height of 9.20 cm without mixing with the water. The question asks for the volume (in cm3) of water that flows out of the right arm.

Figure 14-32 shows a modified U-tube: the right arm is shorter than the left arm. The open end of the right arm is height d = 10.0 cm above the laboratory bench. The radius throughout the tube is 1.30 cm. Water is gradually poured into the open end of the left arm until the water begins to flow out the open end of the right arm. Then a liquid of density 0.830 g/cm3 is gradually added to the left arm until its height in that arm is 9.20 cm (it does not mix with the water). How much water (in cm3) flows out of the right arm?

Can someone help me?

I have no idea how to begin!

How much water will be displaced - as you add a specific volume?
 

Related to How Does Adding a Lighter Liquid Affect Water Displacement in a Modified U-Tube?

1. What is a "Water Flow (Modified U-tube)"?

A "Water Flow (Modified U-tube)" is a device used to measure the flow rate of water or other liquids. It consists of a U-shaped tube filled with the liquid being tested, with one end of the tube connected to a reservoir and the other end connected to a drain.

2. How does a "Water Flow (Modified U-tube)" work?

The flow rate of the liquid can be measured by timing how long it takes for the liquid to travel from one side of the tube to the other. The height difference between the two sides of the tube also affects the flow rate, with a higher height difference resulting in a faster flow rate.

3. What are the main uses of a "Water Flow (Modified U-tube)"?

A "Water Flow (Modified U-tube)" is commonly used in experiments and research to measure and study the flow of liquids. It is also used in various industries, such as plumbing and irrigation, to measure the flow rate of water in pipes and systems.

4. Are there any limitations to using a "Water Flow (Modified U-tube)"?

One limitation of using a "Water Flow (Modified U-tube)" is that it can only measure the flow rate of liquids that are transparent or have a consistent color. It is also not suitable for measuring the flow rate of gases or thick liquids.

5. How is a "Water Flow (Modified U-tube)" different from a regular U-tube?

A "Water Flow (Modified U-tube)" has additional features, such as a reservoir and a drain, that allow for the measurement of flow rate. A regular U-tube is typically used for measuring pressure differences or fluid levels, but not flow rate.
