Steam Boilers, Engines, Nozzles and Turbines In a reaction turbine The pressure and temperature of steam remains constant The expansion of steam takes place partly in the fixed blades and partly in the moving blades The steam is allowed to expand in the nozzle, where it gives a high velocity before it enters 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 The expansion of steam takes place partly in the fixed blades and partly in the moving blades The steam is allowed to expand in the nozzle, where it gives a high velocity before it enters the moving blades The steam is expanded from a high pressure to a condenser pressure in one or more nozzles ANSWER DOWNLOAD EXAMIANS APP
