We were discussing the various types of notches and
weirs i.e. classifications of notches and weirs, difference
between Notches and Weirs, discharge over a triangular notch or weir and
also the expression for discharge over a
rectangular notch or weir, in the subject of fluid mechanics, in our recent
posts.
Reference:
Now we will go ahead to find out the advantage of
triangular notch or weir over rectangular notch or weir, in the subject of
fluid mechanics, with the help of this post.
Triangular notch or weir is always preferred over a rectangular notch or weir due to the following reasons
The expression for discharge for a right angle V-notch
or weir is very simple.
Ventilation of triangular notch is not necessary.
Triangular notch will provide more precise results during measuring low discharge as compare to result obtained from rectangular notch.
Only one reading of H will be required for determination of discharge in case of triangular notch.

Now we
will go ahead to start a new topic in the subject of fluid mechanics i.e.
discharge over a trapezoidal notch or weir.

have any suggestions? Please write in comment box.
