A venturi meter is a device used to measure the flow rate of a fluid through a pipe. It works by constricting the cross-sectional area of the pipe at a specific point, causing an increase in velocity and a corresponding decrease in pressure. The difference in pressure before and after the constriction is used to calculate the flow rate.

In a lab setting, a venturi meter can be used to measure the flow rate of a liquid or gas in a pipe. To do this, the venturi meter is inserted into the pipe and the pressure at the inlet and outlet of the meter is measured using pressure sensors. The difference in pressure is then used to calculate the flow rate using the Bernoulli equation.

One of the main advantages of using a venturi meter is that it can accurately measure the flow rate of a fluid over a wide range of flow rates and pipe sizes. It is also relatively simple to install and maintain, making it a popular choice for flow measurement in various industries.

In conclusion, the venturi meter is a useful device for accurately measuring the flow rate of a fluid through a pipe. It is simple to install and maintain, and can be used to measure a wide range of flow rates and pipe sizes. It is widely used in various industries for this reason, and continues to be a valuable tool for flow measurement.

By plotting the logarithmic measured discharge and measured head loss data points see Figure 3 and determining the linear trend line equation, two constants â€” Î± and Î² â€” can be found. This may be because of parallax error during taking the reading and air bubble trapped inside the tube. . The co-efficient of discharge of a orifice meter. . The picture above shows a venture tube. OBJECTÄ°VE The main objectives of this experiment is to obtain the coefficient of discharge from experimental data by utilizing venturi meter and, also the relationship between Reynolds number and the coefficient of discharge.

. The co-efficient of discharge of a venturi meter The Orifice Meter The orifice meter consists of a throttling device an orifice plate inserted in the flow. Place weight on the balance lever and begin timing and weighing. Thus, pressure would decreases when the velocity increases. The continuity equation is the conservation of mass on a steady flow process through a control volume. . .

. The higher the float position the greater the flow rate. . . The results will deviate from the theoretical ones in real flow due to friction, other imperfections and the measurement uncertainties.

The factors such as heat loss and friction affected the system and prevented the ideal-condition results. Other factors such as human error, air bubbles in the fluid, and calculation round-offs led to discrepancies in the data. ViC took area of cross section into consideration, which when area increase velocity decrease. TQ Volumetric Hydraulic Bench used to power water flow. . . The Cd for the venturi is expected to be greater than that of the orifice.

. Other errors could have been caused by improperly zeroing the testing equipment or allowing air bubbles to remain inside of the Venturi tube, where we could not see them. . Pressure increases and velocity decreases during a flow expansion. Consider a fluid flowing through the pipe having reached equilibrium state, the fluid in the piezometer tube is a non-flow static condition, velocity equals zero.

Figure 4 Flow rate as a function of rotameter height Figure 2 depicts the rotamer height as a function of the flow rate. Table 1: Venturi Data A1 d1 Athroat dthroat 0. Also pulsation of the water being pumped made it difficult to read some of the manometer readings; these were either discarded or averaged with others in order to obtain a more consistent result. . . The flow rate is measured by calculating the time taken to fill the volumetric bench at a constant flow.

. Mass flow rates are calculated five times for each adjustment in flow on the hydraulic bench. The Venturi Meter diameter varies from 26mm inlet to 16mm throat and then back to 26mm outlet , theoretically the pressure at the inlet should be equal to the pressure at the outlet but in the real world we lose pressure dur to head loss. Utilizing the results achieved for the expressions for mass continuity and hydrostatic balance on a fluid column, and the linear momentum equation, the velocities for the Venturi meter at each station can be calculated. The screw is re-tightened when the piezometer has reached a convenient height. In the orifice plate there is sudden decrease in the area of the flow due to restriction of the orifice plate.

The objective is to determine the coefficient of discharge C as a function of Reynolds Number Re and overall head loss as a function of maximum head differential, and to compare each with accepted empirical results. . Analyzing the data acquired, the values attained for velocity and volumetric flow rate are in correlation with the Venturi meter experiment. Engineering 306B â€”Unified Laboratory Manual 2.

. If the pump is turned off, extra air enters the system and needs to be purged prior to proceeding, or else it will produce error in the manometer readings. . The flow rate controlled by a gate valve located at the discharge side of the hydraulics bench. It is intended to be operated in a narrow Reynolds-number range of 1 x 10 5 to 2 x 10 6. .
