The unit associated with it may be considered a derived unit; it is said that such a dimensionless quantity has a coherent derived unit of one. Any ratio of two quantities of the same dimension will be dimensionless, and have dimension one. Thus Mach number and refractive index are dimensionl...
, my interpretation is that a dimensionless quantity cannot be written as empty string but must be written as "1". However, then section 2.8 comes with If there is no unit associated with a quantity (for example a quantity that is a character string, or unitless), data providers should in...
As far as the solid displacement is concerned, we see that (27.37a) is independent of ηˆ and the value uˆηˆ(1,0) is finite. As far as the discharge velocity is concerned, in the purely elastic case (ηˆ=0) the quantity (27.37b) becomes vˆ0(1,0)=2∑n=0∞(−...

Other thing is that you can solve a problem with (for example) Re 2 order of magnitud less. Then probably you can reduce your mesh in this quantity. But then the problem solved will not be the same. When you go back and scale the problem to reality (put in the result the units usi...
In BMA3, system does not allow me to assign EA as base unit if it is a dimensionless unit. Hence, I need to associate EA to a 'dimensional' (e.g. volume) unit. Although I am able to define the calculation of Product quantity from Base quantity after making the CUNI change to EA...

Mass loss rate is a physical quantity describing combustion speed and is generally expressed by the mass loss rate of fuel per unit area (kg/(s ⋅ m2)). In this experiment, the value of the electronic balance was collected every 10s, and the average combustion rate during this period was...
This value should be interpreted as an effective quantity taking into account an increase of attenuation in a powder bed in comparison to fully dense material [33,34]. 2.2. PBF-experiments To get a better understanding of the energy input and distribution during PBF, experimental investigations ...
The number 𝒩𝑍NZ is a dimensionless quantity which measures the overall strength of the electromagnetic field. This number is a useful characterization of the field and its sources. In Section 2, we extend the derivation of the formula for 𝒩𝑍NZ to a general electromagnetic field. In ...
