In this experiment five commonly used devices four conduit and one open channel will be calibrated for water flow. Use the panorama to view the pipe flow rig for this experiment in the laboratory at Mawson Lakes. The first is a magnetic meter, which is simply used to provide an accurate measurement of flow rate against which we will be calibrating the other devices.

These instruments are based on the same principle as following: "The pressure difference between any two points on a tapering pipe through which the fluid is flowing depends on the change of levels and on the change in velocities and therefore on the volume rate of flow" One, the venturi meter, is a device used for measuring the rate of flow of a fluid through a pipe.

Water is allowed to flow through the meter at different rates ranging from zero to the maximum and the corresponding pressure differences shown in the manometer are noted.

The actual discharge is determined using the measuring tank and the stop watch. Figure 1Venturi Meter A Venturi Meter consists of a short converging conical tube leading to a cylindrical portion, called the throat, of smaller diameter of that of the pipeline, which is followed by a diverging section in which the diameter increases again to that of the main pipeline. The function of the converging portion is to increase the velocity of the fluid and temporarily lower its static pressure.

The pressure difference between inlet and throat is developed. This pressure difference is correlated to the rate of flow.

The second, the orifice meter, is again a device used for measuring the rate of flow of a fluid through a pipe. It works on the same principle as a venturi meter.

It consists of a flat circular plate which has a circular sharp edged hole called orifice, which is concentric with the pipe. It has an opening in it smaller than the internal diameter of the pipeline, placed in a flange connecting the two portions of the pipeline. The orifice diameter is about 0. A differential manometer is connected at section 1 which is at a distance of about 1. Figure 2 Orifice Meter The orifice meter comes under the category of "constant area variable head flow meter. Construction of orifice meter is simplest amongst all the flow meters in that it consists of a plate with a hole drilled in it.

In principle, it is essentially similar to a venturi since it obstructs the flow of fluid, however, due to the absence of guiding passage on the downstream passage of the orifice meter fluid comes out in the form of a free jet.

This difference in the flow physics of the two flow meters leads to difference in the value of discharge coefficient and irrecoverable pressure loss even when the area ratios for two are identical. However, in actual practice there are considerablefrictional lossesin orifice meter dueto boundary layer separation and eventual wake formation on its downstream side and actualvolumetricflow rate through orifice meter is less than the theoreticaldischarge.

Observation: Orifice Meter Sr. The principal of this meter is conversion of pressure head into velocity head. Inside the orifices meter due to constriction placed a pressure difference between two sections is developed, which determines the discharge through the pipe. For a given set up the first 3 parameters are fixed so in the experiment we observe the behavior of discharge coefficient with change in Reynolds number.

According to theoretical explication discharge coefficient remains constant for higher Reynolds number. The graph plotted for discharge coefficient verses Reynolds number is very much straight line.

This describes that due to high pressure loss in orifices meter the velocity of flow also get reduced. The graphs of manometer reading verses flow rate were come out to be parabola which was expected theoretically. Venturimeter is a device used to measure the discharge through pipe. The principal of this meter is by reducing the cross section area of flow passes, pressure difference is created and measurement of pressure difference enables the determination of the discharge through pipe.

The discharge through the venture meter is calculated by the formula in the same way as in orifice meter. In comparison of orifice meter, venture meter has less pressure loss. The explanation is that the pressure losses in the convergent section but it pressure regain in divergent section.

There can be error in the measurement of manometer reading. After release the air close the air valves again. Never close the delivery line and by pass line simultaneously. Conclusion: For both meters it was noted from plots that the difference in pressures are directly related to the rate of discharge.

For the Orifice meter the same scheme was noticed but with the ultimate value of 0. Home Venturimeter. Venturimeter 2, 2, KB Read more. Ala 4 0 KB Read more.

Calibration of Venturimeter and Orificemeter

Orifice meters measure flow rates using differential pressure created when a fluid passes through an orifice plate. The flow calculations use a form of the Bernoulli equation with an empirical discharge coefficient. Orifice flow meter calibration helps reduce uncertainty in the discharge coefficient from 0. Orifice meters are normally built to specification from standards such as API Southwest Research Institute performs flow calibrations to lower uncertainty by matching the Reynolds number to the final application. Improved flow measurement improves accuracy for computing plant efficiency, system balances and end-user consumption. Flow calibration of an orifice flange fitting and plate over the application Reynolds number range.

A Venturi meter, an orifice plate meter and a rotameter that demonstrates typical methods of measuring the flow of an incompressible fluid and shows applications of Bernoulli's equation. Students measure flow using a Venturi meter, an orifice plate meter and a rotameter. Students find and compare the head losses for each meter. They also find the losses in a rapid enlargement and a degree elbow. The product has a horizontal pipe that includes a Venturi meter, orifice plate and pressure tappings. An elbow connects the pipe to a rotameter gap-type flow meter with further pressure tappings.

Фонтейн, видимо, размышлял. Сьюзан попробовала что-то сказать, но Джабба ее перебил: - Чего вы ждете, директор. Позвоните Танкадо. Скажите, что вы согласны на его условия. Нам нужен этот шифр-убийца, или все здесь провалится сквозь землю. Все стояли не шелохнувшись. - Да вы просто с ума все сошли, что ли? - закричал Джабба.

Если он использует адрес университета или корпорации, времени уйдет немного.  - Она через силу улыбнулась.  - Остальное будет зависеть от. Сьюзан знала, что остальное - это штурмовая группа АНБ, которая, перерезав электрические провода, ворвется в дом с автоматами, заряженными резиновыми пулями. Члены группы будут уверены, что производят облаву на наркодельцов. Стратмор, несомненно, постарается проверить все лично и найти пароль из шестидесяти четырех знаков.

Когда его торс уже свисал над лестницей, шаги послышались совсем. Он схватился руками за боковые стороны проема и, одним движением вбросив свое тело внутрь, тяжело рухнул на лестницу. Халохот услышал, как где-то ниже тело Беккера упало на каменные ступеньки, и бросился вниз, сжимая в руке пистолет. В поле его зрения попало окно. Здесь.

То, что она увидела, казалось неправдоподобным. Половина лица Хейла была залита кровью, на ковре расплылось темное пятно.

Ошибка в функции цикличности, сотовая автоматика и прочее. ТРАНСТЕКСТ все равно справился. - Время.

Фонтейн поднял глаза, явно удивленный этим сообщением. Мидж подтвердила свои слова коротким кивком. - У них нет света.

 - А мы так и не узнаем, как это сделать. - Захватчики у ворот.

These instruments are based on the pressure difference between any two points on a tapering pipe through which the fluid is flowing depends on the change of levels and on the change in velocities and therefore on the volume rate of flow" Where the flow is led to narrow cross section, at which the velocity increase and hence a fall in the pressure occur.
