Witryna29 maj 2024 · With pressure vessels containing liquid, a portion of the liquid will move as a rigid mass (referred to as the impulsive mass), while the remainder will slosh back and forth (referred to as the convective mass). This behavior will affect the magnitude of the seismic loads on the pressure vessel. Importance Factor ctc in philippinesWitrynaThus, total liquid mass gets divided into two parts, i.e., impulsive mass and convective mass. In spring mass model of tank-liquid system, these two liquid masses are to be suitably represented.

"Witryna20 lis 2024 · The two segments, impulsive mass and convective mass are isolated from complete liquid mass. These two liquid masses should be addressed appropriately in the spring mass model of liquid tank system. The boundary of spring mass model relies on the calculation which was initially proposed by Housner. " - Impulsive mass and convective mass
