Correct: it is a dimensionless number.

A dimensionless number has no units. The units of all variables that compose the dimensionless number (product or ratio) must cancel each other.

Yes, the magnitude of a vector is a scalar.

A dimensionless unit - an integer (or counting number)!

Specific heat is dimensionless, and dimensionless units have the same value in any system. Specific heat is the ratio between two densities - that of the substance considered, and that of water. The ratio of two quantities of the same dimension will naturally be a dimensionless number.

Reynolds number Re is a dimensionless number that gives a measure of the ratio of internal forces to viscous forces and consequently quantifies the relative importance of these two types of forces for given flow conditions

The Reynolds number is a dimensionless quantity used to predict flow patterns in different fluid flow situations. It is defined as the ratio of inertial forces to viscous forces in a fluid flow. A high Reynolds number indicates that the flow is more turbulent, while a low Reynolds number suggests that the flow is more laminar.

If a quantity is "dimensionless", that means it has no units, and it's just a number.

REYNOLDS NUMBER:It gives measure of ratio of the inertial forces to the viscous forces & it is a dimensionless quatity.Physical significance:1.It signifies the relative predominance of inetia to viscous forces.2.It is very useful in determining whether the flow is laminar or turbulent.

No, a dimensionless quantity does not have a unit because it represents a pure number without any physical dimension. Examples of dimensionless quantities include ratios, proportions, and mathematical constants.

The Reynolds number is a dimensionless quantity used in fluid mechanics to predict the flow regime in a system. It helps determine whether the flow is laminar or turbulent. This is important for understanding the behavior of fluids in different scenarios, such as in pipes, around objects, or in boundary layers.

32 is a pure number (integer) and is dimensionless.

the dimensionless numbers have the definition as that of dimensionless groups, and have all the properties which dimensionless groups have.
