The coefficient of contraction in an experiment may be greater than the theoretical value due to factors such as flow imperfections, wall roughness, or turbulence in the flow. These factors can lead to additional energy losses and create a greater contraction in the flow compared to the ideal theoretical case. Experimental conditions and inaccuracies in measurements can also contribute to discrepancies between the observed and theoretical values of the coefficient of contraction.
The coefficient of discharge of a venturi meter is calculated to account for any discrepancies between the theoretical flow rate and the actual flow rate. It helps in correcting for losses due to friction and other factors in the fluid flow, and ensures accurate measurement of the flow rate through the venturi meter.
If the question is, "What is the coefficient of 9b2 ?".......then the answer is 9.
1 whenever there is a coefficient of one then it is not written but "understood"
A coefficient is a number in front of a variable (i.e. multiplied by it).For example, in the expression x2 - 10x + 25, the coefficient of x2 is 1 and the coefficient of x is -10. The third term, 25, is a constant.If the expression were -x2 + 10x + 25, the coefficient of x2 would be -1, and the coefficient of x would be 10.
If the angle is greater than that, the pressure increases too quickly and the adverse pressure gradient will cause flow separation along the walls. By keeping the angle small, the flow remains attached and behaves nicely.
What is the working principle of venturimeter?
Because, the scientist name VENTURI had discover that device as flow measurment. So that it call as venturimeter.

Venturimeter
The average value of the coefficient of velocity for a submerged orifice is typically around 0.97 to 0.99. This value represents the efficiency of the orifice in converting the potential energy of the fluid into kinetic energy.

The tracks have a larger coefficient of linear expansion than the ground beneath.
Measurement of flow rate in a pipe
to measure the flow in any pipes
Venturimeter is the short pipe having two conical parts and portion of uniform cross section between these two parts.
