This principle is used both in Venturi as well as orifice meters. Detailed calculations of uncertainties can be found in Appendix B. On the other hand, orifice plates are easy to make, and are very cheap in comparison. Wall Conducted on: September 17, 2009 Submitted on : September 24, 2009 Abstract: In this lab students experimented with light emitting diodes. The Ho and Hc values were recorded using the piezometer tubes on the side of the meter seen in Figure 5. They are also popular for automatic batching applications.
Such waves can be produced by passing light through polarizing filters. This is actually a special case of Venturi meter and cause more energy losses than Venturi meter. The objective of this experiment is to determine which kinds of habitats potato bugs favor. We ran a series of experiments that generated graphs and equations, which can explain the relationship between voltage and time for capacitors and diodes. Bernoulli's principle, Fluid, Fluid dynamics 1701 Words 6 Pages Theory review…………………………………………………………………………………….
In the orifice plate there is sudden decrease in the area of the flow due to restriction of the orifice plate. In this experiment, students are to adapt to various ways to measure the flow of essentially incompressible fluids by using the flow measuring apparatus. Both flowmeter is often used in applications where it's necessary with higher TurnDown Rates, or lower pressure drops. To compare the difference in flow rate incurred by each of these device. It should be noted that the uncertainty value for the coefficient of discharge that was calculated for method 1 is not a reasonable value.
Zikri Introduction An optical lens is made of transparent material such as glass or clear plastic. However, when tide changes its direction, the water level is likely to stay or little change. The effect that the meter has on the pressure change is termed as the Venturi effect. These bugs are more commonly known as pill bugs and potato bugs. Three fields of study are composed within this memo that includes Electrical Engineering, Environmental Engineering, and Petroleum Engineering. The tank volume scale was taken as true and we did not account for any error in the measurement.
My hypothesis for the urine analysis experiment is that the urine volumes will increase because of the increase of fluids to the body for groups 1 and 3, in comparison with the control group group. Basically, a rotameter consists of a transparent tapered vertical tube through which fluid flow upward. Measure frictional losses due to flows through different valves 3. Whether the tests performed identified specific enzymatic reactions or metabolic pathways, each was used in a way to help recognize those specifics and identify the unknown cultures. Introduction A Venturi meter is a device for determining the flow-rate of a fluid down a pipe.
Another aspect of our results that we can discuss is the linearity of Figure 8 which plots the relationship of Ho values to the volumetric flow rate of the meter. However, there is a significant change in the rise in flow rate when h2 is equal to 170mm and the reason for this change could not be accounted for. Bacteria, Bacteriology, Gram staining 1319 Words 4 Pages Determining Perimeter, Area of a Standard Paper Sheet, Determining Minimum Reaction Time, Uncertainty and Their Propagations Abstract: We conducted two experiments aimed at learning data collection, presentation, interpretation, experimental uncertainties along with their propagation, writing of a scientific report, determination of perimeter, area of a standard printing paper sheet, and determining human reaction times — individual, group and class. They also get very easily installed in all applications. These derivations will be worked out in this section of the report. Based on historical data, we tried to determine, specifically, whether urbanization is a major factor of increased stream flow rates in areas experiencing higher rate of urban development, or urbanization.
In this experiment, required equipment are a water tank, piezometric tubes, pump, a stop watch, empty bucket and a digital weight scale. Casio Chronograph Watch 4000 Rs : 4. The pressure difference generated by the flow velocity through the hole enables the flow quantity to be measured Dictionary. It can be set up to be read locally or remotely using pressure transducers. There are about seven phrases in Du bist wie eine Blume total and none of them are very long.
Venturi vs Orifice Orifice meters and Venturi meters are devices that are used to measure the pressure of flow of fluids. The measured alteration is then related to the flow. According to Michael Reader-Harris n. With a well-calibrated marked glass tube, the level of the float becomes a direct measure of flow rate The venturi meter consists of a venturi tube and a suitable differential pressure gauge. Consider the flow of an incompressible and inviscid fluid through the convergent-divergent Venturi tube.
