3/7/24, 11:02 PM 6.1.2.1 Continuity Equation: Mechanics, Heat, & Sound - HS - Wilkes, Deborah 6.1.2.1 Continuity Equation e Due Feb 23 at 11:59pm Points 14 Questions 14 Available Feb 20 at 12am - Feb 23 at 11:59pm Time Limit None Instructions In this activity, you will develop a qualitative understanding of the continuity equation by exploring a computer simulation. Before you begin, you'll need a computer or tablet and the Phet linked here = pressure-and-flow.htmi?simulation=fluid-pressure-and-flow)_. As you work through the problems consider the following Guiding Questions: 1. What is happening as the pipe changes shape? Smaller? Larger? 2. What property of the pipe are you changing as you change the size of the pipe? 3. What happens to the velocity of the fluid as you change the shape of the pipe? Smaller? Larger? 4. What rule are you developing? You will be asked to submit a photo of your work at the end of this assignment. You can download and print the original handout here (https://onramps.instructure.com/courses/3820435/files/265668215/download? download_frd=1). This quiz was locked Feb 23 at 11:59pm.

3/7/24, 11:02 PM 6.1.2.1 Continuity Equation: Mechanics, Heat, & Sound - HS - Wilkes, Deborah Submitted Feb 22 at 5:24pm This attempt took 8 minutes. Question 1 1/1pts Open the Fluid Pressure and Flow PhET simulation. Go to the second tab - “Flow” Explore how you can change the flow rate by moving the slider. What are you changing when you change the flow rate? Explain in words. Your Answer: liters per second through the pipe Question 2 1/1 pts What do you think happens to the flow rate as the fluid moves throughout the pipe? Your Answer: Stays the same Drag the arms on the side of the pipe to create three different shaped pipes. Upload your three unique designs below. Design | Picture 1 You will submit your solution in the Upload section at the end of this assignment. Question 3 1/1 pts Use the tools available to study what happens to the pressure and speed of the fluid as it moves along the pipe. What conclusions can you make regarding how the properties of the pipe affect the speed of the fluid in the pipe? *Use one of your examples from above as your evidence* https://onramps.instructure.com/courses/3820435/quizzes/10615046 2/11

3/7/24, 11:02 PM 6.1.2.1 Continuity Equation: Mechanics, Heat, & Sound - HS - Wilkes, Deborah Your Answer: Smaller diameter of the pipe the speed increases curves do not affect the speed Question 4 1/1 pts How does velocity of the fluid change as the pipe becomes smaller? The velocity... Correct! increases. decreases. stays the same. More information needed. Question 5 1/1 pts How does velocity of the fluid change as the pipe becomes larger? The velocity... increases. Correct! decreases. stays the same. More information needed. Question 6 1/1 pts What physical property of the pipe are you changing by making the pipe larger or smaller? Your Answer: Diameter/ cross-sectional area https://onramps.instructure.com/courses/3820435/quizzes/10615046 3/11

3/7/24, 11:02 PM 6.1.2.1 Continuity Equation: Mechanics, Heat, & Sound - HS - Wilkes, Deborah Question 7 1/1 pts What is the mathematical term that describes this property? Volume Density Correct! Cross-sectional area Length Consider the following image - A Answer this following questions with this information. Question 8 0/1pts How does the flow rate at A compare to B? You Answered The flow rate of A is slower than B. The flow rate of A is faster than B. Correct Answer https://onramps.instructure.com/courses/3820435/quizzes/10615046 4/11

3/7/24, 11:02 PM 6.1.2.1 Continuity Equation: Mechanics, Heat, & Sound - HS - Wilkes, Deborah The flow rates are the same Question 9 1/1 pts How does the velocity of the fluid at A compare to B? *Use the simulation to confirm your prediction™ Correct! The velocity at A is slower than the velocity at B The velocity at A is faster than the velocity at B The velocities are the same. Question 10 1/1 pts What is different about the pipe at A compared to B? Your Answer: The diameter / cross-sectional area Question 11 1/1 pts What is different about the pipe at A compared to B? Correct! The cross-sectional area at A is greater than the cross-sectional area at B. The cross-sectional area at B is greater than the cross-sectional area at A. There are no differences. Question 12 1/1 pts If you were to write in words a rule for how the fluid compares at A to B that includes the properties of the pipe and the velocity of the fluid what would it say? Your Answer: The velocity of the fluid increases as the diameter/ cross section area decreases Question 13 1/1 pts Upload: https://onramps.instructure.com/courses/3820435/quizzes/10615046 5/11
