Discharge Characteristics of Parshall Flumes under Submerged Flow Condition

The four different sizes of Parshall flumes having throat width as 0.052 m, 0.076 m, 0.152 m and 0.229 m were tested in laboratory under submerged flow condition. Coefficient of Parshall flume (C) and exponent (n) of discharge (Q) – head relation (H) for all four different sizes of flumes were determined with the help of MATLAB Programming. It was shown that a unique relationship can be developed except for 0.229 m size flume.
