WitrynaThe impulsive mass mi and the convective masses mc are of fraction of the total liquid mass m. For practical applications, only the first convective mode of vibration needs to be considered in the analysis of mechanical model. The natural period of vibration of the impulsive mass is from 0.1 s to 0.3 s and that of the convective mass from 2 s ... Witryna1 wrz 2012 · The impulsive part of response can be calculated by replacing the boundary condition given in Eq. (16) with the boundary condition specified in Eq. (17). Having obtained the total and impulsive response values, the convective response is the difference between these two values.
