characteristics associated with water and air flowing vertically upwards was investigated through a bed of coarse ballotini (glass beads with a nominal diameter of 485 microns).Different flow rates for water and air is applied to determine the pressure drop and differentiate between the fixed bed and the fluidized bed characteristics. Also the measured onset of fluidization was compared with the predicted one. From this experiment it was obtained thatthe pressure drop increase as increasing the fluid (water

EXPERIMENT 3: ISENTROPIC EXPANSION PROCESS Objective In order to demonstrate the isentropic expansion process. Introduction Isentropic means no change in entropy. Entropy is a thermodynamic property that is the measure of a system’s thermal energy per unit temperature that is unavailable for doing useful work. In simple terms‚ the measure of the level of disorder in a closed but changing system‚ a system in which energy can only be transferred in one direction from an ordered state to a disordered

Catalase Experiment Research Question: How does the weight of a piece of liver (0.4g‚ 0.8g‚ 1.2g and 1.6g in this case) affect the amount of gas created after 2 minutes when combined with hydrogen peroxide? Aim: To see find out how the amount of catalase correlates with the amount of gas created when in combination with hydrogen peroxide. Materials: 15g of liver 25 ml of hydrogen peroxide 1 scale 1 bucket 1 100ml graduated cylinder 1 250ml flask with bung 1 50cm tube (able to fix onto top of flask)

For this experiment‚ we started off by taking tubes numbered 1-4 and started adding one scoop of our enzyme catalyst‚ in this case‚ the yeast. We then proceeded to measure and add 1 mL of distilled water to test tubes A-D. To get a more accurate measure of 1 mL of distilled water‚ we used the dropper labeled “W” to drop distilled water into the 5 mL graduated cylinder until we saw that the bottom of the water line reached closely to 1 mL. Next‚ we took the four tubes with the scoop of yeast and

Physics 1003 Experiment Report In this experiment‚ the technician began with the demonstration of solar energy. Solar energy is the conversion of light energy to electrical energy by using solar panels. Solar panels are devices that contained solar module which use light energy from light to generate electricity through the photovoltaic effect. And photovoltaic modules generate electricity from a frequency of light. From my observation of the experiment‚ I found that the panel is black in

Lab Report - Microbes Aim: To investigate four areas of the school and to find out which of the four have the most microbes. Areas to Sample: 1. Girl’s locker room (Senior school) 2. Girl’s locker room (Elementary school) 3. Boy’s locker room (Senior school) 4. Boy’s locker room (Elementary school) Hypothesis: We predict that the boy’s locker room in the senior school will have the most microbes. First of all‚ there are more people using our locker rooms in the Senior School

Science Lab Report Conclusion Ms. Seaward Jeneé S. White May 16‚ 2015 How Light Refracts Throughout Water My experimental question for my project is: Would light bend at a refractive angle after it propagates through water? The resolution to my experimental question is that light does bend at a refractive angle after it propagates through water. My hypothesis for my project is: I hypothesize that light will bend because of real world examples and experiments. One instance is light refracts

prevents the backflow of blood. Blood enters the heart through the inferior and superior vena cava carrying deoxygenated blood. The vena cava then empties into the right atrium. When the right ventricle is relaxed‚ blood flows from the atrium into the right ventricle. The blood is then pushed through the pulmonary semilunar valve into the pulmonary artery where it carries deoxygenated blood to the lungs for oxygenation. The blood then flows back into the heart from the lungs into the left atrium

“There are only two ways in which humankind can produce knowledge‚: through passive observations or through active experiment.” To what extent do you agree with this statement? Word count: 1255 Candidate name: Alexander Shum Candidate number: 0049330018 I fully agree the statement in the question. In my opinion‚ I believe that the production of knowledge requires both passive observation and active experiment. Both of them are heavily linked together‚ and are part of a larger process
