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.

accuracy; reliability.
No. Quality and accuracy are incredibly important to scientists. If an experiment is not performed with quality and accuracy it is not valid. However, if accuracy is not especially important, possibly because the result will be the same, then it can be ignored.
Accuracy refers to the closeness of a measurement to the true value. It indicates how well a measurement matches the actual value being measured. The accuracy of a measurement is important in ensuring the reliability and validity of experimental results.
A bulb pipette class A has an accuracy of 0,02 mL.
The accuracy of a measurement does not depend on the weight being measured. Instead, accuracy is a measure of how close a measured value is to the true or expected value. To determine the accuracy of a measurement in pounds, you would need to compare the measured weight of 20570 pounds to the actual weight or reference standard.
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.
Increased accuracy and power.
Venturimeter
Measurement of flow rate in a pipe
Increased matching accuracy and increased number of matches
to measure the flow in any pipes
Use more expensive equipment with better sensitivities.
Lots of people did this; the accuracy increased over time.
Increased matching accuracy and increased number of matches
Increased matching accuracy and increased number of matches
Venturimeter is the short pipe having two conical parts and portion of uniform cross section between these two parts.
