Want this question answered?
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
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.
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.
coefficient
2X 2 is the coefficient
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.
The coefficient of friction is a scalar quantity which has no direction which does not have an angle.
A discharge coefficient is used to account for inaccuracies resulting from assuming plug flow and neglecting friction in the Bernoulli equation.
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.
The coefficient of friction is dimensionless; it has no units.

No. Coefficient of friction is not measured in units.
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
