Why the value of correlation coefficient is always between -1 and 1?
A serious error. The maximum magnitude for a correlation coefficient is 1.The Correlation coefficient is lies between -1 to 1 if it is 0 mean there is no correlation between them. Here they are given less than -1 value so it is not a value of correlation coefficient.

Yes it is. If all the observations have the same non-zero value then the coefficient of variation will be zero.

approximately equal to 0.6
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.
The average value of the coefficient of velocity for a submerged orifice is typically around 0.97 to 0.99. This value represents the efficiency of the orifice in converting the potential energy of the fluid into kinetic energy.
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.
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
The numerical value that comes before the variable or, if none, the coefficient is 1.The numerical value that comes before the variable or, if none, the coefficient is 1.The numerical value that comes before the variable or, if none, the coefficient is 1.The numerical value that comes before the variable or, if none, the coefficient is 1.
A coefficient has a fixed value, unlike a variable in an expression.
The coefficient is the numerical value attached to an unknown or a variable. Thus, the coefficient of 8x is 8.
A coefficient in front of the absolute value sign means to multiply that coefficient by the absolute value in the problem. For instance 3*ABS(-3) = 3*3 = 9.
Why the value of correlation coefficient is always between -1 and 1?
The lower the value of the coefficient of friction, the lower the resistance to sliding.
