# Flow measuring apparatus report

The equipment has three water circuits with instruments, pipes and pipe system components. These allow students to examine and compare the different component characteristics. The Digital Hydraulic Bench H1F, available separately supplies the circuit with a controlled flow of water. ## Airflow Measurement Apparatus - Forced Air Systems

FM is designed to measure a flow of an incompressible fluid. From this experiment, we will obtain the flow rate measurement with comparison of pressure drop by utilizing three basic types of flow measuring techniques; ratometer, venture meter and orifice meter. Actual flow rates for the water is determined by using a constant volume of 10L and the time taken for the water to reach until 10L for each experiment.

We could compare the flow rates of the flowmeter based on the results we get from the graph. It shows that venturi meter is more accurate compare to orifice meter which the flow rates of venturi meter is closer to the actual value of the flow rates.

On the whole, our experiment was successfully done because we has achieved the objective of the experiment. FM apparatus is designed to operate together with a basic hydraulic bench or a water supply.

This enables students to familiarize themselves with typical methods of flow measurement of an incompressible fluid. This apparatus will allow students to compare between different types of flow measurement devices, namely by using a venturi device, orifice device and rotameter.

The data obtained can be further used to compare against measurement obtained from the hydraulics bench. Other feature of the flow apparatus includes a 90 degree elbow with pressure tappings.

This feature allows students to calculate the total head loss and loss coefficient when fluid flows through the 90 degrees elbow.

In short, the apparatus allows the following experiment to be carried out: Besides, to investigate the loss coefficient of fluid flow through 90 degree elbow. Other than that, to determine the total head loss of fluid flow. Basically, a rotameter consists of a transparent tapered vertical tube through which fluid flow upward.

When there is no flow, the float rests on a stop at the bottom end. As flow commences, the float rises until upward and buoyancy forces on it are balanced by its weight.

The float rises only a short distance if the rate of flow is small, and vice versa. The points of equilibrium can be noted as a function of flow rate.

## How to Measure Velocity of Air

With a well-calibrated marked glass tube, the level of the float becomes a direct measure of flow rate. The venturi tube has a converging portion, a throat and a diverging portion as shown in the figure below.

The function of the converging portion is to increase the velocity of the fluid and lower its static pressure. A pressure difference between inlet and throat is thus developed, where pressure difference is correlated with the rate of discharge. The diverging cone serves to change the area of the stream back to the entrance area and convert velocity head into pressure head.

In metering practice, this non-ideality is accounted by insertion of an experimentally determined coefficient, Cd,termed as the coefficient of discharge.36 SOLTEQ® FLOWMETER MEASUREMENT APPARATUS (FM) Page 1 ABSTRACT SOLTEQ® Flowmeter Measurement Apparatus (Model: FM) is designed to measure a flow of an incompressible fluid.

From this experiment, we will obtain the flow rate measurement with comparison of pressure drop by utilizing three basic types of flow measuring techniques. CHE M Experiment No. 3 LIQUID FLOW MEASUREMENT flow-measuring devices commonly used in the laboratory and in industry while performing calibration procedures.

The experiment is designed to study uniform water flow over a range of flow rates. Open the water supply valve to the apparatus 2) Open the air supply valve to .

Air flow measurement instruments, anemometers, have been limited in the past by time. The newest microprocessor-based anemometers complete duct air flow measurement data collection accurately even before the patience of the HVAC tech wears out. The purpose of this experiment is to investigate the flow rate/discharge and the head loss of 3 particular flow measuring apparatus which are the Venturi Meter, Orifice Meter and Rota Meter in accordance to Bernoulli’s Equation.

Conclusively, fluid flow rate can be determined by several methods using the flow measuring apparatus and relating to the Bernoulli’s Equation. The mass flow rate of. Flow Measuring Apparatus Report Essay Introduction The flow measuring apparatus is used to familiarize the student with typical methods of flow measurement of an incompressible fluid and, at the same time demonstrate applications of the Bernoulli’s equation.
