- Difference between theoretical equations and empirical equations
Other equations are empirical in the sense that they were selected only because they fit experimental data and without a theoretical justification If we look at an equation can we identify whether it is a theoretical equation or an empirical equation just by looking at the equation?
- Calculation of collapse pressure of steel pipe | Eng-Tips
I am using the paper "A new empirical formula for collapse resistance of commercial casing" by T Tamano, T Mimaki and S Yanaimoto This empirical model included the effect of tolerances, residual stress and seems pretty good
- The semi-empirical formula and $E=mc^2$ - Physics Stack Exchange
The semi-empirical mass formula (SEMF) is much more involved than this, and tries to take into account various other factors that will affect the mass energy of the nucleus For any nucleus, of course if you KNOW its mass beforehand then simply subtracting the individual masses of protons and neutrons will give you ($\pm$)the binding energy, but the SEMF at least tries to be more predictive
- Empirical formulas for compressive yield strength? | Eng-Tips
I work with a diversity of materials The properties of these materials aren't always well known in websites like MatWEB, Campus plastics Compressive Yield Strength is seldom given for most materials, even common ones Despite that, I need that property in my calculations Is there some
- Derivation of the Antoine equation - Physics Stack Exchange
The vapour pressure $P^0$ of a pure substance can be approximated by a semi-empirical formula called the Antoine equation, which says $P^0$ is related to the
- collapse pressure of casing tubing | Eng-Tips
I meant to post here, but accidently posted it first in the ASTM forum Anyway My question is about how to calculate collapse pressure of steel casing or tubing including imperfection effects, such as tolerance, residual stress, etc I am using the paper "A new empirical formula for collapse
- Semi-empirical mass formula - Physics Stack Exchange
The formula is for the mass of the nucleus, so you would need to add on the mass of the electrons (and subtract their binding energy) to get the mass of the atom However, as previous questions have mentioned, the mass of the electrons is a small correction and in fact generally smaller than the errors in the semi-empirical mass formula
- nuclear physics - How does the semi-empirical mass formula prove or . . .
The semi-empirical mass formula (SEMF) is a better estimator of atomic mass than the standard mass formula, which neglects spatial arrangement of nucleons and resulting interactions
