In the present study, a number of nozzles have
been examined on the openings of a tank wall to show behavior of the
flow through it. The flow was measured at different nozzles for variable
water heights in the tank, the flow lines were marked in d
ifferent cases. A
modification was made to the geometric shape of the nozzles, the
measurement and drawing of the different flow curves were carried out.
In this paper, an oblique side weir was studied by nine models installed at the entrance of
side channel at an angles (300,450,600,750 and 900) respected to side channel wall and installed at
two directions, with flow direction and opposite it. The
models were tested by five different flows
passing over them so, the number of runs is 45.
The hydraulic characteristics of flow over vertical and oblique side weir were studied, and
the results show increasing of discharge over side weir when installed at an oblique direction
and the average increases when their inclination at left direction was greater (6%) than that
right direction.
Equations were predicted for calculation of discharge coefficient (Cd) and coefficient of
energy loss (k) for two directions and the water surface profile for vertical and oblique side weir
in two directions is plotted.
