Change in Pressure and Different Depths in a Static Fluid Lab Essay Example for Free

Change in draw and Different Depths in a Static Fluid Lab EssayPurposeThe purpose of this science lab is to devise a correlation between that of the data we have collected from our experiment and compare it to that of theory. In this experiment 3 different tests were done in order to test this theory. The first test was to tie a surge on the end of a manometer and measure the pressure at different depths in a large beaker filled with pissing. The next test was the same thing, but without the balloon on the end of the manometer. For the final test a pressure reckon was used to measure the pressure at different depths in the water. The data collected from each experiment was the depth of the object and its deviance. To find out the metaphysical pressure for the experiment this equation will be used P=H2ODepthThe theoretical results will then be compared to the measured results, determine the correlation between both sets of data in order to prove whether or not this experim ent is capable of proving the theory.Procedure1) Fill the cylinder with water and adjust the manometer to read zero. 2) For first test tie a balloon to the end of the tube that gives the manometer reading, and fill it with air. 3)Immerse the balloon in the water and measure the deflection at each specific depth (Try to get as close as you posterior to 11, 9, 7, 5, 3, and 0 inches). 4)When finished with the first test remove the balloon and proceed to second test. 5) For the second test immerse the (balloon free) manometer tube in water, also measuring each specific depth and deflection. 6) For the third test instead of measuring with the manometer use a pressure gauge to measure your deflection (make sure you set the gauge to zero before testing).CalculationsTest 1 modelDepth 3.5 inchesDeflection 1.7 inchesP.

From looking at the graph I notice that as we moved on to the second and third tests there seemed to be less and less error. In general I think that human error had a huge impact on this lab. If we could have done a few trials for each test I think that the outcome of our measured results would be a lot closer to those of the theoretical results.What we were attempting to do with this lab was take the theoretical results of our experiment and get them as close as we could to the measured results with niggling percent error in order to determine if this test was reliable. By comparing some of the results I can safely say that this test is valid. virtually of the data comparisons are far off, but others are within 2 percent error and I know for a fact that better results can be acquired.
