(mm)/second use the following formula: Vv = (Dp-p x rpm)/27.01 where: Dp-p = peak-peak displacement in mm (in.) Vv = Vibration velocity in mm (in.)/second rpm = motor speed 2) peak-peak displacement Speed-torque curves show the rated performance of the servomotor in a 40 ...
Instead of using the Green–Kubo formula [8] to compute the thermal conductivity k by integrating the time autocorrelation of the heat current J, this quantity can be computed using an equivalent Einstein relationship for the diffusion of the energy momenta—that is, the mean-squared displacement...
The thermal transmittance from one room to another in a building cannot be calculated with the aid of simple approximate formulae due to the fact that the internal walls have a more complicated thermal exchange with the room air, the external wall elements and surrounding rooms. A calculation of...
This proposed formula for the retrieved effective surface conductivity is representative for asymmetric dielectric layers. In this work, we only consider the normal incidence of electromagnetic waves on the metasurface in a symmetric environment (i.e. the metasurface in a free space) since the absorpt...

The following formula, from the Nyquist sampling theorem, provides a rule of thumb for pipe discretization into a minimum of N segments: N=2Lfc, where: L is the Pipe length. f is the transient frequency. c is the speed of sound. For some applications, you may need to connect Pipe (...
The formula for the adiabatic temperature increase is given in equation 1 and for TMR in equation 2. Here ∆Tad is the adiabatic temperature increase, ∆h the specific enthalpy of reaction, and cp the specific heat capacity at constant pressure. ...

Adsorbed gas in-place is then calculated using the formula below:mad=ρmρg0VLPP+PLwhere mad is the gas adsorption mass per unit volume of formation (kg m−3), ρm is shale matrix density (kg m−3), ρg0 is gas density at standard condition (kg/scf). In general, Langmuir ...
however it is an often-used formula to describe the thermal inertia of a material.Table 3.2shows the impact of different materials and frequencies of the absorption coefficient. The thermal inertia,I, of a material is defined as the square root of the product of the material’s thermal conduct...
