Suction Specific Speed, coupled with "Suction Energy", can be used to determine the maximum pump speed for an application to avoid excessive and damaging cavitation. Ideally pumps should be operated with low "Suction Energy", and an NPSH Margin Ratio of at least 1.3, both of which can be achieved with slower pump speeds.

The Bond ball mill grindability test measures hardness as an index, regardless of the feed size, so it does not give credit for the additional fines. Therefore, the index itself is ignored in the analysis and the results are assessed in terms of throughput rate or specific energy requirement.

In physics, binding energy (also called separation energy) is the minimum energy required to disassemble a system of particles into separate parts. This energy is equal to the mass defect minus the amount of energy, or mass, that is released when a bound system (which typically has a lower potential energy than the sum of its constituent parts) is created, and is what keeps the system together.

The gas constant is also known as the molar, universal, or ideal gas constant, denoted by the symbol R or R and is equivalent to the Boltzmann constant, but expressed in units of energy per temperature increment per mole, i.e. the pressure–volume product, rather than energy …

This then implies that the entropy of the system is given by: where c is some constant. The value of c can be determined by considering the limit T → 0. In this limit the entropy becomes S = klog Ω0 where Ω0 is the ground state degeneracy. The partition function in this limit is where U0 is the ground state energy. Thus, we see that c = 0 and that:

• Specific Energy (Wh/kg) – The nominal battery energy per unit mass, sometimes referred to as the gravimetric energy density. Specific energy is a characteristic of the battery chemistry and packaging. Along with the energy consumption of the vehicle, it determines the battery weight required to achieve a given electric range.
