Cajote 201030149 Jacqueline Faye D. Centrifugal pump, Density, Dimensional analysis 1580 Words 6 Pages Mechanic Lab Layout Name Of Apparatus 1. Fluid flows through a length of pipe of varying diameter. These will be used to determine the hydraulic grade line of the fluid as it passes through the manometer. Understanding the graphical representation of. Thus any gain in a fluid may accrue due to its increased velocity through a constriction is balanced by a drop in pressure. From the result, I learn that the water level and tide have positive relationship.

## Orifice, Nozzle and Venturi Flow Rate Meters

Prove that for any flow the reading is unaffected by the slope of the meter. As you progress further in science, you will see variations in styles of lab reports, though they all contain the same basic principles. The Venturi Tube and Orifice Plate are basically used to determine flow rate in piping systems. These reports can contribute a significant amount of marks and yet little time or attention is devoted in understanding on how to write them well. The pressure at the entrance to the meter is gauge and it is undesirable that the pressure should at any point, fall below absolute.

## Report: Venturi meter



Overview In engineering and industrial practice, fluid measurement of many of the variables and properties, such as density, viscosity, pressure, velocity, flow rate and etc is one of the problems most frequently encountered by engineers. As a rule the article this way of measuring on the anxiety that could be, how we identify the price of the doubt is offered within experimental approach area, even so, you also ought to provide skepticism after a benefit-minus warning sign when offering the end results. Introduction A Venturi meter is a device for determining the flow-rate of a fluid down a pipe. You can be a fantastic scientist, able to produce great results inside lab, but when you are can not correspond these types of successes comfortably to the next someone, all of the lab talents are worthless. The Final Results portion is not simply an accumulation of data files tables and information, but have to encompass prose paragraphs as anyway.

## Lab Report for Venturi Meter

The output section is never compared with them. Designs One of the significant benefits of the Venturi meter is that the design can be modified to fit almost any requirement, and it can be constructed with a broad range of materials depending upon application and the matter that will be measured. At the end of the system, a mixture of liquid and gas will appear. Interactive codes foster performance evolution because they provide a basic structure and design from which creative engineering minds can contemplate then execute beneficial changes. By measuring the change in pressure, the flow rate can be determined, as in various devices such as venturi meters, venturi nozzles and. The flow area is at a minimum at the throat.

For a final check, shut off the flow into the Venturi meter and make sure all of the water levels are the same. By operating the pump to keep the water is full in the water. Typically, the energy loss through a Venturi meter is between 0. In addition, unless there is a change to the internal geometry of the Venturi meter, the discharge coefficient will not change. The closed conduit is often circular, but may also be square or rectangular, such as a heating duct.

## The Benefits Of A Venturi Meter

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. The effect of changing weight, shape, and radius of the objects balloons were tested independently such that it would be clear under what criteria either laminar or turbulent air flow is prevalent. You drop a small steel ball from various heights and use an electronic timer to measure how long it takes the ball to hit the ground. In a flow metering device based on the the downstream pressure after an obstruction will be lower than the upstream pressure before. Bengtson References for further information: 1. Make sure you also summarize the most important results of the play with it.

Repeat step 5 two more times with the difference in water levels between ½ and ¼ of what it was in step 3. 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. The design of the Modified Short Form Venturi can be constructed with reduced manufacturing costs for the manufacturer. Furthermore, we also explored their behavior when they were connected in different configurations. Other types of liquid flow meter are the rotameter, magnetic flow meter, ultrasonic meter, turbine flow meter and coriolis flow meter. When the hydrate metal salt crystal is heated, the attractions to the water are broken by the heat energy and the water escape from the crystal. In addition, Venturi meters can be oriented in any plane and can measure accurately whether the line fluid is flowing upwards or downwards.

## Pipe Flow Measurement with a Differential Pressure Flow Meter like the Orifice or Venturi Meter

Because of the smooth gradual transition down to the throat diameter and back to the full pipe diameter, the friction loss in a venturi meter is quite small. If a pump forces the liquid through a tube connected to a system consisting of a venturi to increase the liquid speed the diameter decreases , a short piece of tube with a small hole in it, and last a venturi that decreases speed so the pipe gets wider again , the gas will be sucked in through the small hole because of changes in pressure. The Venturi effect is a jet effect; as with an air funnel, or a thumb on a garden hose, the velocity of the fluid increases as the cross sectional area decreases, with the correspondingly decreasing. This means that there are no downstream straight pipe requirements for standard accuracy, the meters have lower headloss, are less susceptible to blockages and plugging, and are extremely accurate, which can be field verified. Such an sense is definitely terrible for a scientific paper or perhaps an engineering offer, all of which will as required be labeled back down inside lab report.

Theory: A Venturi meter and an Orifice are both instruments used for measuring the rate of discharge for a fluid flowing in a pipe. Tube which was connected to the venture meter outlet was further connected to the measuring tank. The latter is typically available from the meter manufacturer. This lab aided students in observing kinematics by giving them a visual graph to look at from experiments previously performed. Absorbance, Absorption, Chemistry 1240 Words 6 Pages Introduction The purpose of this lab was to identify unknown bacteria cultures using various differential tests, and my unknown bacteria is 17. The effect that the meter has on the pressure change is termed as the Venturi effect.

These improvements, and many more made since the mid-1960s, are the result of continual design refinements by top manufacturers who methodically applied knowledge and careful testing processes to even the most minute change. However, when tide changes its direction, the water level is likely to stay or little change. Type these results up in a spreadsheet and include them in the report. Use a direct application of Bernoulli's theorem taking the relative density of mercury to water as 13. After heating the salt crystal is called as anhydrous, which. However, the Insert Venturi meter design with a static high pressure tap off of the center flange and into the upstream spool piece has the same installation insensitivity as the traditional flanged, full body Venturi design at the proper static pressure sensing location.
