FLOW MEASUREMENT BY VENTURI METER AND ORIFICE METER
3 For measurement through venturi, open the outlet valve of the venturi meter line and close the valve of the orifice meter line 4 For a good amount of variation in discharge, close the by-pass valve of pump also 5 Now switch on the pump 6 Open the gate valve and start the flow 7
Venturi meter - Prexams
1 The Venturi meter _invented by Clemens Herschel in 1886_ is the best apparatus used to measure the flow of water in a large pipe having little if any head loss It is named after the Italian philosopher Giovanni Battista Venturi who created in 1796 a theory saying that water flowing through a pipe
Use of Venturi Meters in Multiphase Flow Measurement
to measure the differential pressure in order to be able to calculate the flowrate In multiphase flow, however, although the densities of the individual component phases are known, the den-sity of the multiphase mixture is not known Therefore it is necessary to measure the density of the fluid mixture entering the Venturi meter
Measurement of fluid flow by means of venturi tubes Flange or
User guide – venturi tube - Rev 1 March 2017 - Page 3 C – Venturi tube installation / Installation des venturis I Location / Emplacement Tag number / Numéro du tag Check the tag number of the venturi tube to be sure that the item is the right one to be mounted Vérifier le tag sur le venturi de façon à s’assurer qu’il
A Simple, Inexpensive Venturi Experiment – Applying the
vertical tube was used to measure the pressure at the end of the hose A 70 in x ¾ in ID (180 cm x 1 9 cm ID) Tygon® tube was used to connect the outlet of the tee to the venturi meter The ID of the venturi (at the end of the funnels) was measured by inserting a 3/8 in (0 953 cm) metal tube, which fit snugly through the ends of the funnels
Venturi Apparatus - UTSA
The Venturi Apparatus includes two rubber stoppers with holes Use one of them to connect the hose of the shop vacuum to the inflow port of the apparatus (see Figure 5) Connect the hose to the air-blowing port of the shop vacuum To measure airflow, connect a spirometer sensor as described on page 9
