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.

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.
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.
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.
