Experiment Paper

Our objective for the Sherlock Holmes Experiment was to illustrate that some chemicals can be identified or differentiated by simple chemical tests, such as solubility, pH, or color tests. In our group we had to test come common powders such as Alka-Seltzer, baking soda, flour, Vitamin C (ascorbic acid), and salt. Other chemicals that were used to do this experiment were vinegar, and Iodine 2 Solution. The equipment used to do this experiment was red litmus paper, and 5 test tubes per group.

Students will carefully observe acts of aggression and prosocial behavior on television, report their observations, and analyze their data to draw conclusions.

Ever since graphene has been found, scientists began to wonder how the substance will play a huge role in our future. Predicting which sector graphene can improve is easy. With the prior knowledge from previous experiments, the characteristics found could be used to formulate a list of industrial sectors where the specific characteristics would be useful. However, the experimentation for these hypotheses require countless amount of experimentation. In most cases, graphene would be mixed with several other useful materials to create a composite material. These added materials could make the composite material stronger, lighter, harder, etc. Unfortunately, these added materials may also bring in unfavorable changes. Furthermore, nobody

As seen in the table, there is a broad range of resistivity values for various materials. Those materials with lower resistivities offer less resistance to the flow of charge; they are better conductors. The materials shown in the last five rows of the above table have such high resistivity that they would not even be considered to be conductors.

As shown in figure 1 , schematic diagram of the experimental apparatus is shown. The three pipes used in the fabrication of the heat exchanger are made of brass(inner pipe), copper pipe(helical pipe), mild steel pipe(outer pipe). The inside diameters of the three pipes are 0.03175m, 0.009525m and 0.0635m respectively with thickness of each pipe as 1.5mm only. The experimental set up is composed of a test section, normal water loop, cold water loop, hot water loop and temperature measuring system. The water is used as working fluid. The test section and the connections of piping system are designed such that parts can be changed for different flow arrangement. The hot water loop consists of a storage tank, an electric heater of 3000W immerged inside the storage tank to obtain the high temperature of hot water, a pump and gate valve. The cold water loop consists of a storage tank, a pump and gate valve. Ice cubes are used to cool down the temperature of tap water to nearly 130 C . The normal water loop consists of storage tank, pump and gate valve. After the temperature of the water is adjusted to the desired level, the normal, cold and hot water are pumped out of the storage tank and are passed through test section and discharged to outside. The flow rate of the water are controlled by adjusting the valve and measured by the flow metres of +_ 0.2% of full scale. The heat exchanger is a concentric tube

Background & theory: In this experiment, the relationship between volumetric flow rate and percentages of valve opening is determined by knowing that volumetric of flow rate of air through the flow meter is proportional to the square root of the differential head across the manometer. Graph of volumetric flow rate (%) vs valve opening (%) can

The current EC system used for graphite conductivity profiling and sub-surface crack detection is based on a commercial instrument known as Solartron Impedance Analyser. This system can only take a single frequency measurement at a time, since the current methods is based on a multi-frequency measurement this take a long time to acquire a full set of multi-frequency measurements required for conductivity reconstruction and crack detection. From a practical point of view, a slow measurement system is also associated with an increased cost as this could increase the overall inspection time of the reactor core. Therefore, the future work in this area could be an investigation of suitable system that allow a measurement of the multi-frequency

The “Smart Tool” was used to determine the ratio of the voltage-current at each point, and the observation was recorded.

Ohm’s law defines the relationship between three important electrical properties namely: voltage, current and resistance. Mathematically, ohm’s law is expressed as: V=IR. By understanding the importance of conduction, one is able to determine the total resistance and visualize how resistors are connected in parallel circuits. In parallel connection, each resistor provides a separate path for current [I] so that the total resistance of a parallel circuit is reduced as more resistors are connected in parallel. In contrast, the resistance in series circuits increases when more resistors are introduced into the circuit. This

To be competitive as renewable energy recourse turbines in wave energy generation must be robust and economical for a number of years. Approaches utilize experiments to characterize and predict the effect of parameters involved. One of which is advancements to turbine blades due to unsteady hydrodynamic loads. Characterizing these loads can determine their fatigue life and determine a more reliable material to be used for manufacturing the blades avoiding premature failure. Reliability is necessary due to most renewable wave energy devices are being placed in remote locations where it is not economical to maintain or replace failed hardware. Turbulent flow across the turbine blade creates moments and bending of the blades

methodology based on the work of Brocklehurst [94] has been attempted to assess the ability of the reconstruction algorithm to calculate conductivity profiles

In this investigation the experiments are perform in three stages. In the first stage experiments are performed by using Taguchi method in order to maximize the desirable performance parameter and minimize the undesirable performance parameter. In the second stage, experiments it carried out by using one factor- at-a time approach. In this approach first set the optimum process parameter as a constant and adding the Graphite powder concentration from 1 to 21 gm/lit in the dielectric fluid. And identify the effective powder range for Inconel 718 alloy material. In third stage, experiments are performed by response surface methodology by addition of different graphite powder concentration in the dielectric fluid.

The graphite conductivity profiling work in this thesis has extended the feasibility studies carried out on the previous projects related to AGR core inspections. The work was initially approached with the extension of the existing RGN algorithm through the implementation of the new constraining techniques based on a priori information of the sample graphite electrical conductivity gradient. The new constraining technique was mainly implemented to deal with the non-linear and ill-posed nature of the inverse EC problem as well as the model calibration errors. The results from this study produced a substantial improvement in the accuracy (a minimum global error of 1.3 %) of the reconstructed electrical conductivity profile of the sample graphite brick using experimentally measured data. In addition to producing accurate profiles, the new constraining techniques reduced the amount of computational time by an average of 60 % compared to the unconstrained cases.
