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

Why is the coefficient of discharge of a venturimeter calculated?
The coefficient of discharge of a venturi meter is calculated to account for any discrepancies between the theoretical flow rate and the actual flow rate. It helps in correcting for losses due to friction and other factors in the fluid flow, and ensures accurate measurement of the flow rate through the venturi meter.
Why you need coefficient of discharge?
The coefficient of discharge is needed to account for energy losses and inefficiencies in fluid flow systems. It helps to adjust theoretical calculations to more closely match real-world conditions, resulting in more accurate predictions and designs for fluid flow applications.
Why the value of coefficient of contraction is greater then the theoratical value in experiment?
The coefficient of contraction in an experiment may be greater than the theoretical value due to factors such as flow imperfections, wall roughness, or turbulence in the flow. These factors can lead to additional energy losses and create a greater contraction in the flow compared to the ideal theoretical case. Experimental conditions and inaccuracies in measurements can also contribute to discrepancies between the observed and theoretical values of the coefficient of contraction.
What is value of coefficient of viscosity of glycerin?
The value of the coefficient of viscosity of glycerin is approximately 1.5 Pa.s (pascal second) at room temperature. Viscosity measures a fluid's resistance to flow and is influenced by factors such as temperature and pressure.
What term is used to refer to the process of electrical discharge and the flow of electrical activity?
The term used to refer to the process of electrical discharge and the flow of electrical activity is "electric current." It is the flow of electric charge through a conductor, such as a wire, and is measured in amperes (A).
What are the factors that affect the value of coefficient of discharge?
Factors that affect the value of coefficient of discharge include the geometry of the orifice or nozzle, roughness of the opening, fluid properties such as viscosity and density, and the flow regime (e.g., laminar or turbulent flow). Additionally, the presence of obstructions or inlet/outlet conditions can also impact the coefficient of discharge.
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.

What will happen to the coefficient of discharge if the tube is shorter than the standard length or the head causing the flow is relatively high?
If the tube is shorter than the standard length or the head causing the flow is relatively high, the coefficient of discharge will likely decrease. This is because a shorter tube or higher head can lead to increased friction losses and turbulence within the system, impacting the efficiency of the flow measurement. In practical terms, this means that the actual flow rate may be lower than the expected flow rate, resulting in a lower coefficient of discharge.
Why coefficient of discharge is less than one?
The coefficient of discharge (Cd) is less than one because it accounts for energy losses in a fluid flow system, such as turbulence, viscosity, and friction as the fluid exits a nozzle or orifice. These losses prevent the fluid from flowing at the ideal or theoretical flow rate, which is calculated based on the cross-sectional area and pressure. Consequently, the actual flow rate is reduced compared to the theoretical flow rate, resulting in a Cd value that reflects this efficiency.

What will happen to the coefficient of discharge if the tube is shorter than the length or the head causing the flow is relatively high?
If the tube is shorter than the required length or if the flow is high, the coefficient of discharge may decrease. This is because the flow may become more turbulent and the accuracy of the flow rate measurement may be affected. Generally, for accurate measurements, it is important to ensure that the tube length and flow conditions are within the specified parameters.
What are the average values of these coefficient for a sharp crested orifice?
The average discharge coefficient (Cd) for a sharp crested orifice typically ranges from 0.6 to 0.7. This value can vary based on factors such as the orifice geometry, flow conditions, and the fluid properties. In practice, a Cd of around 0.62 is often used for calculations involving sharp crested orifices in open channel flow.
Why the value of coefficient of contraction is greater then the theoratical value in experiment?
The coefficient of contraction in an experiment may be greater than the theoretical value due to factors such as flow imperfections, wall roughness, or turbulence in the flow. These factors can lead to additional energy losses and create a greater contraction in the flow compared to the ideal theoretical case. Experimental conditions and inaccuracies in measurements can also contribute to discrepancies between the observed and theoretical values of the coefficient of contraction.

An austausch coefficient is a coefficient of turbulent flow in eddies.
What is value of coefficient of viscosity of glycerin?
The value of the coefficient of viscosity of glycerin is approximately 1.5 Pa.s (pascal second) at room temperature. Viscosity measures a fluid's resistance to flow and is influenced by factors such as temperature and pressure.
