No. It is not possible to accelerate a gas to a supersonic velocity in a converging nozzle.
Since it is a nozzle the speed of flow could reach to be sonic velocity through convergent section .But after that the flow couldn’t increase and the velocity due to that the convergent section work as diffuser for supersonic velocity.
Converging nozzle can’t produce supersonic flows due to the compressibility effect of gases. Bernouillis relation no longer holds here.
For accelerating a fluid to a supersonic velocity a diverging section is to be added.
