Cover Page Please provide a cover page, you may use the one in ODTUCLASS or you may create another one. 2. Introduction (15 pts] Please mention the purpose, the significance and the use of the test. You may consult to the related ASTM standard. 3. Equipment (5 pts] You can directly copy from the Lab Manual. 4. Test Procedure [5 pts] You can directly copy from the Lab Manual. 5. Calibration Steps (5 pts] You can directly copy from the Lab Manual. 6. Calculations (15 pts] Please make sure that you use the correct data assigned specifically to your section and group in ODTUCLASS. Please follow the same format in the Hydrometer Test Data Sheet, which is given in the Lab Manual. You need to show one row of the calculations in detail (Please show how to calculate Psusp, P, H, D, etc.) 7. Results & Discussions (55 pts] Please provide The completed version of the Data Sheet (given in the Lab Manual) as a table, Grain size distribution graph (created with the data on the table, do not forget the log-scale), The amount of clay-sized particles (percent), Limitations of the test (you may write both the errors that you observed during the test, or the theoretical limitations)
