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 else can I help you with?
What conditions the value of coefficient of discharge be greater than one?
The coefficient of discharge (Cd) can exceed one in certain conditions, typically involving flow measurement devices like orifices or nozzles where the flow is accelerated significantly. This can occur due to effects such as compressibility of the fluid, particularly with gases, or when flow conditions lead to a reduction in pressure and an increase in velocity that is not accounted for in the traditional equations. Additionally, measurement errors or assumptions in the theoretical models can also contribute to a Cd greater than one. However, for most incompressible fluids in controlled environments, Cd is typically less than one.
When one factor in a multiplication problem is less than one is the product greater or less than the other one?
When one factor is less than one, the product will be less than the other factor.
Is three fourths and two thirds greater or less than one?
It is less than. You see if its not one whole than its less than one.

Why vane coefficient is always less than 1?
It isnt, for deflection angles b less than 90o, Cvane should be greater than 1.0, while for angles greater than 90o, it should be less than 1. Alot of times it is less then one because it is the ratio between the actual force and ideal force. Factual/Fideal. Since friction acts on the actual force, it is going to be less then the ideal force, resulting in a number lower than one.
What Are The Properties Of Regression Coefficient?
(a) Correlation coefficient is the geometric mean between the regression coefficients. (b) If one of the regression coefficients is greater than unity, the other must be less than unity. (c) Arithmetic mean of the regression coefficients is greater than the correlation coefficient r, provided r > 0. (d) Regression coefficients are independent of the changes of origin but not of scale.
Properties of regression coefficient-statistics?

Is one quarter more or less than one third?
one quarter is less than one third
What does it mean when the coefficient of performance in a refrigeration cycle is less than 1?
The COF will always be less than 1 a little confusing as im getting more than 1 with calculations at the moment, but i know its always less than one, its what the lectures at the university have told me. I am assuming if it is more than one you take the inverse of that number but im not sure, im looking for more information. its kind of like a percentage for efficiency. you cant have 110% efficient.
When one factor in a multiplication problem is less than one is the product greater or less than the other one?
When one factor is less than one, the product will be less than the other factor.
If a demand for a product is elastic the value of the price elasticity coefficient is?
greater than one
Is three fourths and two thirds greater or less than one?
It is less than. You see if its not one whole than its less than one.
Is there economic inequality in the US?
YES. This is currently a huge social issue in the US and galvanizing support for the Democratic Party. The US currently has a GINI coefficient of 0.477. (A GINI coefficient of 0 is perfect economic equality and a GINI coefficient of 1 is that all wealth in a country is concentrated in one person.) A GINI coefficient of 0.477, which is higher than the GINIs of all European countries, indicates a moderate degree of economic inequality, but something less than the high economic inequality of most third-world countries.
The lower the value of the coefficient of friction what is the resistance to sliding?
The lower the coefficient of friction, the lower the resistance to sliding between two surfaces. A lower coefficient of friction means that it is easier for one surface to slide past the other with less force or effort required.
Is ninety five hundredths less than one or greater than one?
less than one
