ADVANTAGE OF TRIANGULAR NOTCH OVER RECTANGULAR NOTCH

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. 

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

Do you have any suggestions? Please write in comment box.
