Dimensionless numbers allow you to compare two systems that are vastly different by combining the parameters of interest.
For example, the Reynolds number, Re = velocity * length / kinematic viscosity. If you are testing an airfoil with a particular Re, and you want to run a simulation on a scaled-down model (length is smaller), you could increase fluid velocity or lower kinematic viscosity (change fluids) or both to establish the same Re and ensure you are working under comparable circumstances.

RafaDimensionless numbers allow for comparisons between different systems without being affected by the units used. They provide insight into the physical behavior of systems and can help predict how they will respond to changes in parameters. Dimensionless numbers also help simplify complex problems and reveal underlying relationships between variables.

Perfect numbers between 20 and 30?
There are no perfect numbers between 20 and 30. Perfect numbers are numbers that are equal to the sum of their proper divisors, excluding the number itself. The perfect numbers within this range would be 28, but that is incorrect as 28 is not a perfect number.
Who highlighted the importance of observational learning?
Albert Bandura is a psychologist who emphasized the importance of observational learning in his Social Learning Theory. Bandura argued that individuals can learn new behaviors by observing others and then imitating those actions.

Is the ratio of two natural numbers always positive?
No, the ratio of two natural numbers can be positive, negative, or zero depending on the numbers being divided.
Which numbers are square numbers?
Any numbers that can be written as the product of some number with itself e.g.: 1 = 1*1 4 = 2*2 9 = 3*3 16 = 4*4 100 = 10 * 10 There are an infinite number of square numbers so you can't expect a comprehensive list.
