Venturimeters, Flow through Elbows, Discharge Coefficient, Reynolds Number


The performances of venturimeters with different throat diameter ratios have been evaluated experimentally and their influence on discharge coefficient for Reynolds number are studied. The experiments are conducted using water as working fluid for incompressible flow situation. The effects of locations of elbows at different upstream distances from venturimeter are investigated. Five different beta ratio (0.2, 0.3, 0.4, 0.5, and 0.6) venturimeters are considered. The upstream distance from the elbow to the venturimeter of 1D, 2D, 3D, 4D, 5D, 8D, 12D, 16D, and 20D are considered during the experimentation. From the study, it is seen that the discharge coefficient of a venturimeter is nearly independent of Reynolds number. The values of the discharge coefficient and Reynolds number are affected by the upstream length when the upstream length is of 1D & 2D.
