Click "Run Sun now" to start the simulation. Notes for Today Use Pascals for your unit of pressure. Remember, [Pa] = [iz] For all of your pressures today, use four significant figures for your answers. For example, if the pressure meter gives you 101.325 kPa you can write that as 101,300 Pa. Part 1: Atmospheric Pressure Setup Ruler In the top right hand corner, select the grid option for the simulation. Grid Using the sliding knob, fill the pool so that there the water is 3 meters deep Make sure that the acceleration due to gravity is equal to 9.8 m/s2 Click the pressure meter to control it. Drag the pressure meter to ground level and determine the pressure at the ground. Record this value in the space below. Patm = Pa This value is the atmospheric pressure; because that is the pressure you feel when one atmosphere is on top of you. Where do you think the atmospheric pressure is the least? Denver, CO (1609 m above sea level) [Ocean City, NJ (0 meters above sea level) Death Valley, CA (86 meters below sea level) [Hillsborough, NJ (45 meters above sea level) Explain your response:45OF Clear ~ 9: ( () 1:21 AM 2/12/2022 Name: (90 pts max) Date: Results : Part II: Calculating Pressure To determine the absolute pressure of a static (unmoving) fluid, we can apply the following concept. Summarize this formula in words. P = Po + pgh gasoline? For this next part you'll have to decide what type of person you are. Do you want to jump into a pool full of honey of Gasoline (po = 700 kg/m3) Honey ( ON = 1420 kg/m ' ) Justify your response: So now that you've made your decision, predict the gauge pressure 3.0 meters below the surface of your fluid. Show your work in the space below. Check your answer by using the simulation. Part III: Fluid Flow Setup Pressure Flow \\Water Tower Click on the 'Flow' Tab Experiment with the simulation for at least 2 minutes. Experiment with every variable you can until you are familiar with the simulation. Okay. It better be at least 2 minutes later. We're going to talk about mass flow rate and volume flow rate, which are two ways to talk about fluids flowing. Setup Reset All Click on the 'Reset All' button Mass flow rate, ", is the mass of the fluid passing through a pipe in a given second. In physics, mass flow rate is measured in - Volume flow rate, ", is the volume of the fluid passing through a pipe in a given second ults: (90Name: Date: Results: (90 pts max) What do you think volume flow rate is measured in in physics? In the current simulation, the volume flow rate is 5000 L/s, or 5 m /s. This means that 5 cubic meters of water are passing through the pipe in a second. If the density of this water is 1000 kg/m', answer the following questions. 1. What is the volume of water that flows through the pipe in 6 seconds? 2. What is the mass flow rate of the water? 3. What is the mass of the water that flows through the pipe in 6 seconds? Part IV: Continuity The mass flow rate and the volume flow rate are always the same in a closed pipe. Why do you think that has to be the case? (Try and think about what might happen if the rates were not the same). Setup Select the 'Flux meter' option Flux meter Drag the pipe so that you have areas of 12.5 m?, 10.0 m, 5.0 m, 2.5 m, and 1.0 m What do you notice about the volume flow rate at different points along the pipe? What do you notice about the speed of the water at different points along the pipe? When is the water the fastest?Name: Date: Results: (90 pts max) The slowest? Use the simulation to fill in the table below. Area (m?) Speed (m/s) Volume Flow Rate (m3/s) 1.0 2.5 5.0 10.0 12.5 Determine the continuity formula, which relates two points where fluid flows in a closed pipe. Answer the questions below about water moving through a closed pipe. 1. Determine the speed at which water would flow through a point in the pipe that has a cross sectional area of 0.25 m' and a volume flow rate of 5.0 m3/s. 2. Determine the speed at which water would flow through a point in the pipe that has a cross sectional area of 0.25 m' and a volume flow rate of 10.0 m'/s. 3. Determine the speed at which water would flow through a point in the pipe that has a cross sectional area of 1.0 m' and a volume flow rate of 10.0 m /s. 4. Determine the speed at which water would flow through a point in the pipe that has a cross sectional area of 1.0 m' and a volume flow rate of 20.0 m /s.Date: Results: (90 pts max) Name: Making Connections 1. Where would fluid flow the fastest in the following pipe segment (Point 1 or Point 2)? Explain your reasoning. 2. A garden hose has a diameter of 2 cm and water enters it at 0.5 m/s. You block 90% of the end of the hose with your thumb. How fast does the water exit the hose ? 3. The blood speed in a normal segment of a horizontal artery is 0.15 m/s. An abnormal segment of the artery is narrowed down by an arteriosclerosis plaque to one-half the normal cross sectional area. What is the difference in blood pressures between the normal and constricted segments of the artery? 4. Why do all houses need a plumbing vent? 5. How do airplane wings work (even paper airplanes)
