A tank is filled with water to various depths, h. The pressure, P, at the base of the tank is measured for each depth of water. The results are as follows. Depth of water, h (m) Pressure at base, P (kPa) a. C. b. Using the guidelines above, plot a full size, accurate graph of the data. Use your graph to estimate the water pressure at a depth of 2.2 m. e. 0 0.50 1.0 1.5 2.0 2.5 3.0 0 0.40 0.85 1.3 1.7 2.0 2.5 d. Extend your graph to estimate the depth needed for a pressure of 2.7 kPa, f. Does the water pressure depend upon the depth or does the water depth depend upon the pressure? Hence write down the dependent variable. 9. Use your graph to describe the relationship between water pressure, P and depth, h. Write a full sentence. Calculate the gradient value of your graph. Hence write down an equation for the relationship between P and h.
