|In a sharp-crested weir, the thickness of weir is kept less than half of the height of water on the weir.|

|2L < H.
L < H/2.
= length of sharp - crested weir.

Length of sharp, hight of water in the weir.

|In a sharp-crested weir, the thickness of the weir is kept less than half of the height of water on the weir.
B = thickness of the weir.
H = height of water above the crest of the weir.
The Discharge equation for a sharp-crested weir remains the same as that of rectangular weir & rectangular notch.
Q = 2/3 Cd X b Root of 2g X H2/3.

|The thickness of a sharp-crested weir is generally much thinner such as in using a Plate.|

|In a sharp-crested wear, the thickness of the wear should be less than half of the water of wear.
Q= 2/3CdL √2g h3/2.
|Kavita said: (Aug 5, 2021)|
|The thickness of the shaft crested wear kept less than half of the height of the water on the wear B<H/2.|
