Measurement of stiffness of rock from laboratory and field tests Naeem O. Abdulhadi & Amjad F. Barghouthi Arab Center for Engineering Studies (ACES) ABSTRACT This paper compares the deformation modulus of rock measured from laboratory and field tests which were carried out as part of the site investigation works for a major project in Irbid‚ Jordan. Laboratory resonant column and torsional shear tests were performed at different confining pressures whereas ultrasonic velocity tests were

Discussion for Experiment 1 (Basic Laboratory Operations and Identification of a compound : Chemical Properties) In the first experiment‚ the precision of instrument was studied by measuring the mass of water for several times. The result shows that the mass measurement of the balance is precise since the masses of water in six trials are somewhat close. The reason that the masses of water in each trial are not identical may come from the high sensitivity of the balance that keep fluctuating due

This is followed by the list of objectives of the experiment‚ telling exactly what was expected from the laboratory and what information we wanted to gather from the experiment. The theory section explains the logic behind some of the formulas used and results gathered. The experiment as a whole is discussed with the experiment’s method explaining all the

Laboratory 3. Empirical Formula Of An Oxide This experiment will demonstrate the law of conservation of mass‚ and more specifically‚ how the law can be used to experimentally determine the empirical formula of our intended product‚ magnesium oxide. In this experiment we will learn how to: 1. heat a sample in a crucible with a Bunsen burner. 2. use the method of weight by difference to determine mass quantities. 3. convert grams to moles. 4. determine the simplest ratio between two

Laboratory Report: Flame Colors of Metals Abstract The experiment about flame color of metals demonstrates how electrons jump into their excitedstate from their ground state as it came in contact with heat. As it return to its lower energy state‚it emits the absorbed energy in the form of light. A platinum or nichrome wire was dipped into aconcentrated HCL and was heated to clean it. The wire was dipped into different salt solutionsand heated in order to determine the metallic ion’s color and wavelength
