as we know during experiments, we cant go with or have the actual accuracy requried same here heads are not properly maintaied constant during exeperment.
coefficient of velocity is 0.97 coefficient of discharge is varied from 0.80 to 0.64 coefficient of contraction is 0.64 thanks to me later .do your assignments
repeat your experiment a few times!! that's it, easy.
It would be pointless doing the experiment and not measuring accurately

Using the correct rules is always the best method for getting accurate results.
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.
A discharge coefficient is used to account for inaccuracies resulting from assuming plug flow and neglecting friction in the Bernoulli equation.
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.

approximately equal to 0.6
Why is it important to have an accurate data in a experiment?
When doing a controlled experiment, you get accurate results.
so your answer is accurate
repeat your experiment a few times!! that's it, easy.
