![]() ![]() Discuss your results, focusing on the following:.Plot the measured force from the weights ( W) versus the force of the water on the deflector ( F y) that is calculated by using the momentum equation, i.e., Equation 2.Compare the slopes of this graph with the slopes calculated from the theoretical relationship from Equation 5.Record the slopes in the Results Table, as the experimental slope. Prepare one graph, presenting the results for all three deflectors, and use a linear trend line, setting the intercepts to zero, to show this relationship. Plot a graph of velocity squared, v 2, (x-axis) against applied weight, W, (y-axis).Your report should include the following: Use the template provided to prepare your lab report for this experiment. Repeat the entire test for each of the other two flow deflectors. ![]() Repeat this procedure by adding an additional 50 grams incrementally, until a maximum mass of 500 grams has been applied.You should collect water for at least one minute to minimize timing errors. This is achieved by closing the ball valve and measuring the time that it takes to accumulate a known volume of fluid in the tank, as measured from the sight glass. Measure the flow rate, using the volumetric tank.Observe and note the flow behavior during the test. Open the bench valve slowly, and allow water to impinge upon the target until the datum line on the weight pan is level with the gauge.Place a mass of 50 grams on the weight pan, and turn on the pump.Check that the position is correct by gently oscillating the pan. With no weights on the weight pan, adjust the height of the level gauge until it aligns with the datum line on the weight pan.Ensure that the vertical shaft is free to move and is supported by the spring beneath the weight pan.The nuts should only be tightened enough to level the plate. Do not overtighten the knurled nuts, as this will damage the top plate. Replace the three knurled nuts, then tighten in sequence until the built-in circular spirit level indicates that the top plate is horizontal.Using the spirit level attached to the top plate, level the cylinder by adjusting the feet.Replace the top plate on the transparent cylinder, but do not tighten the three knurled nuts.Connect the inlet tube to the quick-release connector on the bench.Replace the cylinder, and screw the 90-degree deflector onto the end of the shaft.Remove the top plate (by releasing the knurled nuts) and the transparent cylinder from the equipment, and check and record the exit diameter of the nozzle.Perform the experiment by taking the following steps: \)Ī YouTube element has been excluded from this version of the text.
