Explanation:
Coefficient of Velocity for Sharp-Edged Orifices:
- The value of the coefficient of velocity for sharp-edged orifices is typically around 0.98.
- This value is used to account for the velocity of the fluid as it exits the orifice, which is higher than the theoretical velocity due to the contraction of the jet.
- Sharp-edged orifices are commonly used in flow measurement devices such as orifice plates.
- The coefficient of velocity helps to correct the theoretical flow rate calculations to account for the actual flow conditions.
- The coefficient of velocity is based on empirical data and is specific to the type of orifice being used.
- It is important to use the correct coefficient of velocity for accurate flow rate calculations in engineering applications.
This is why the correct answer to the question is option 'B' - 0.98.

Coefficient of velocity:
It is defined as the ratio of the actual velocity of the jet at veena contracta V to the theoretical velocity Vth.
Experimentally it is determine by using the following relation
where x= Horizontal distance
y= vertical distance
h= constant head water
Generally the value of Cv varies from 0.95 to .99 for different orifices depending upon their size, shape, head etc. for sharp edged orifices the value of Cv is 0.98.
