1st Part: Information:

A)

Purpose: To determine the effect of i} density and ii) surface height on hydrostatic pressure. Hypothesis: Predict the effect of i) density and ii) surface height on hydrostatic pressure. Explain your prediction using the concepts of fluid statics you have learned in this activity. Materials: Interactive tank simulation with three substances to choose from: a water {p = 1000 kg.\" m3): 0 glycerine (p = 1250 kgrmis} and 0 olive oil (p = 850 kgrm3l Procedure: Part A Effect of Density on Hydrostatic Pressure 1. Choose a surface height to which the tank is filled. Record this surface height. You will use this same level for all three substances in this part. The surface height to which the tank is filled is 10. 2. Fill the tank to the desired surface height with water. PM the tank to 7. 3. Record the substance filing the tank and the hydrosta ic pressure that results. Water Glycerine Olive oil 67915 Pascals 84892.5 Pascals 57726.9 Pascals . Choose a substance to fill the tank. You will use this same substance for all three surface heights in this part. Olive Oil- Surface Heights: 8,9, and 10. . Fill the tank to a low middle and high surface heights. . Record the surface height and the hydrostatic pressure that results] Olive Oil Surface Height: Hydrostatic pressure Low: 8 67306.4 Pascals Middle: 9 1732203 Pascals High: 10 84133 Pascals . Create a graph from your results from Part A. The graph should include density on the horizontal axis and hydrostatic pressure on the vertical axis. . Analyze the graph of your results from Part A. What is the effect of density on hydrostatic pressure? . Create a graph from your results from Part B. The graph should include surface height on the horizontal axis and hydrostatic pressure on the vertical axis. . Analyze the graph of your results from Part B. What is the effect of surface height on hydrostatic pressure? . Select one of your three results from Part B (a surface height and hydrostatic pressure pair). Complete a calculation to determine the density of the substance you chose to work with in Part B. . Compare the density you calculated to the density that was given for the substance in these instructions. Are they the same when expressed to the proper number of significant digits? . The bottom of the tank has a diameter of 'l .2 m. For the result you chose to work with in question 6. use the density equation to determine the mass of the substance that was in the tank. Remember that the volume of a cylinder can be calculated by multiplying the area of its base by its height. . For the result that you chose to work with in question 6, use the pressure equation to determine the weight ofthe substance that was in the tank
