Difference between a constant and a coefficient?
Ya mum Constant are numbers which has no units (EG: PYE which is 22/7) . They are just numbers. Where as coefficients have units. . where as Coefficient like alpha the thermal coefficient has units .It is so many mm/meter/ deg C
Is coefficient of discharge constant?
No coefficient of discharge is not constant. It is a function of many parameters like :The ratio of the length of the orifice to diameter of orificeReynolds numberflow condition-whether it is increasing or decreasingPressure at the exit of the orifice (back pressure)Orifice entry condition- like smooth entry, sharp edged entry etc.
What do you mean when you say that the coefficient of variation has no units?
Suppose the mean of a sample is 1.72 metres, and the standard deviation of the sample is 3.44 metres. (Notice that the sample mean and the standard deviation will always have the same units.) Then the coefficient of variation will be 1.72 metres / 3.44 metres = 0.5. The units in the mean and standard deviation 'cancel out'-always.
Example of coefficient?
coefficient
What is an example of coefficient?
2X 2 is the coefficient
What is the coefficient of discharge?
Coefficient of discharge of an ideal liquid can be defined as a ratio of actual discharge and theoretical discharge. where, Cofficient of discharge = Actual Discharge/ Theoretical discharge.
What are the units of the coefficient of friction?
The coefficient of friction is a scalar quantity which has no direction which does not have an angle.
Why is the coefficient of discharge of a venturimeter calculated?
A discharge coefficient is used to account for inaccuracies resulting from assuming plug flow and neglecting friction in the Bernoulli equation.
Why is coefficient of discharge of venturi meter is more than coefficient of discharge of orifice meter?
In Venturi meter losses are less so coefficient of discharge is higher whereas in orifice meter due to no convergent and divergent cones there are more losses and hence its coefficient of discharge is less.In venturi meter losses are low due to steamline shape of the diffuser and the pressure gradient is not abrupt as in case of orifice meter.
What are the units that friction is measured in?
The coefficient of friction is dimensionless; it has no units.
What is the value for coefficient of discharge for a rectangular notch?
.623
What is the value of coefficient of discharge for rectangular notch?
.623
Is the coefficient of friction up to 13 unit?
No. Coefficient of friction is not measured in units.
What is the average value of coefficient of velocity in a submerged orifice?
coefficient of velocity is 0.97 coefficient of discharge is varied from 0.80 to 0.64 coefficient of contraction is 0.64 thanks to me later .do your assignments

What represents the number of units of each substance taking part in a reaction?
synthesis
What is the value of coefficient of discharge for v notch?
approximately equal to 0.6
