7.3.2.2.2 Energy conservation (power supply)

Assuming that the mass balance requirement is obtained, the pressure at plunger tip, and gate velocity, , increase (and can reach infinity,(when then ) when the plunger diameter is reduced. Therefore, the energy supply to the system has to be infinity (assuming a constant energy dissipation, actually the dissipation increases with plunger diameter in most ranges)to make a question in regards to dissipation and velocity However, the energy supply to the system (c.v. only the liquid metal) system would be (finite amount) and the energy the system provide plus would be infinity (infinite gate velocity) plus dissipation.
