**Educational Content: Understanding Venturi Meters**

**Part A**

Find the flow velocity measured by a venturi meter (refer to Figure 1).

*Express your answer in terms of some or all of the variables \( P_1, A_1, P_2, A_2, \) and \( \rho \).*

Input field for velocity \( v_1 = \)

**Part B**

A venturi tube is measuring the flow of water; it has a main diameter of 2.9 cm tapering down to a throat diameter of 1.6 cm. If the pressure difference is measured to be 31 mm-Hg, what is the velocity of the water?

*Express your answer to two significant figures and include the appropriate units.*

**Figure Description**

The figure illustrates a diagram of a venturi meter, which shows the flow of fluid through a pipe that has a narrowing (constriction). 

- **P1** and **P2** represent pressure gauges positioned before and after the constriction.
- **A1** is the cross-sectional area of the pipe before the narrowing, while **A2** is the area at the narrowing.
- **v1** and **v2** represent fluid velocity at these respective points.
- Arrows indicate the direction of fluid flow through the venturi meter.

This setup is used to measure fluid velocity by observing the pressure difference caused by the change in cross-sectional area.
