A dimensionless quantity may have a unit (like radians for angles) or may not have a unit at all (like strain). 4. Strain as a Dimensionless Quantity: - Strain is defined as the change in length divided by the original length (ΔL/L). Since both ΔL and L are lengths, the ratio...

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...
As far as the power density is concerned, in the purely elastic case (ηˆ=0) the quantity (27.37c) becomes Pˆ0(0)=2∑n=0∞1=+∞. Thus, we see that, in the purely elastic case, both discharge velocity and power density exhibit a blow-up at tˆ=0 in the case where the...

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,...

The Sieder–Tate correlation analyzes the system as a nonlinear boundary value problem and needs to be solved iteratively, as the viscosity factor changes as the Nusselt number changes. These examples demonstrate that a quantity does not have to be expressed as an explicit function to be subject...
