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.

What is coefficient of contraction for venturimeter?
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.
The closeness of a measurement to its true value is a measure of its .?
accuracy; reliability.
Why pressure is more at throat than at inlet in venturimeter?
In a venturimeter, the pressure is lower at the throat than at the inlet due to the principle of conservation of energy and Bernoulli's equation. As fluid flows through the venturi tube, it accelerates in the throat, leading to an increase in velocity and a corresponding decrease in pressure. This phenomenon occurs because the cross-sectional area is smaller at the throat, causing the fluid to speed up, which results in a drop in static pressure according to Bernoulli's principle. Thus, the pressure at the throat is lower than at the inlet.
Quality and accuracy are not important to scientists.?
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.
Closeness of a measurement to the true value?
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.

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.
