The coefficient of contraction (Cc) for a venturimeter is the ratio of the area of the throat (narrowest section) to the area of the inlet (largest section). It accounts for the loss of fluid flow due to the contraction as the fluid passes through the throat, typically ranging from 0.6 to 0.9 for most venturimeters. This coefficient is crucial for accurate flow rate calculations and reflects the efficiency of the venturimeter design in maintaining fluid velocity.

Why the value of coefficient of contraction is greater then the theoratical value in experiment?
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.
Why is the coefficient of discharge of a venturimeter calculated?
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.

What is a coefficient?
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.
What is general range of coefficient of discharge for venturimeter?
The coefficient of discharge (Cd) for a venturimeter typically ranges from 0.95 to 0.99. This high value indicates that venturimeters are efficient flow measurement devices, with minimal energy losses during fluid flow. The exact value can vary based on factors such as fluid properties, flow conditions, and the design of the venturimeter.
Why the diverging angle is smaller than converging angle for a venturimeter?
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.

How the loss coefficient K can be calculated for sudden contraction?
The loss coefficient ( K ) for a sudden contraction can be calculated using the formula: [ K = \left(1 - \frac{A_2}{A_1}\right)^2 ] where ( A_1 ) is the cross-sectional area of the larger duct and ( A_2 ) is the cross-sectional area of the smaller duct. This formula assumes that the flow is incompressible and that the contraction is sudden, leading to turbulence and energy loss. The resulting ( K ) value represents the energy loss due to the abrupt change in flow area.
