How do you calculate coefficient of variation?
The coefficient of variation is usually calculated by diving the standard deviation by the mean of a particular set of data. The coefficient of variation is usually expressed as CV.
How can the accuracy of a venturimeter be increased?
Reduce errors by using a discharge coefficient to account for inaccuracies resulting from assuming plug flow and neglecting friction in the Bernoulli equation. Also ensure that the device is horizontal or replace the pressure term with "P + static head" if a horizontal device is not possible.

Does the value of the coefficient of discharge depends on the flow rate?
coefficient of discharge depends on the state of the machine/system you are using. if you are using very textured tubes then this number will be higher. if how ever you are using very flexable tubes and fluid at different pressures this can also effect your results as the inflow and outflow may be different, or the cross sectional area of the tubes again chganging the pressure/flow and thus you Cd value
What is venturi meter?

What is the coefficient of discharge?
Coefficient of discharge of an ideal liquid can be defined as a ratio of actual discharge and theoretical discharge. where, Cofficient of discharge = Actual Discharge/ Theoretical discharge.

Why is coefficient of discharge of venturi meter is more than coefficient of discharge of orifice meter?
In Venturi meter losses are less so coefficient of discharge is higher whereas in orifice meter due to no convergent and divergent cones there are more losses and hence its coefficient of discharge is less.In venturi meter losses are low due to steamline shape of the diffuser and the pressure gradient is not abrupt as in case of orifice meter.

Why venturimeter is called venturimeter?
Because, the scientist name VENTURI had discover that device as flow measurment. So that it call as venturimeter.
