the steam is allowed to expand in the nozzle, where it gives a high velocity before it enters the moving blades

the expansion of steam takes place partly in the fixed blades and partly in the moving blades

the steam is expanded from a high pressure to a condenser pressure in one or more nozzles

the pressure and temperature of steam remains constant
