| Abstract: | We propose to derive relations for the motion of a piston, taking into account the variation of its mass due to the additional mass of the gas entrained by the motion of the piston. We show that the gas entrained by the piston has an appreciable effect on the acceleration of the piston and the acceleration length, with the piston attaining a velocity close to the limiting value.Translated from Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti i Gaza, No. 5, pp. 167–169, September–October, 1971. |
