Steam Boilers, Engines, Nozzles and Turbines In a reaction turbine 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 steam is allowed to expand in the nozzle, where it gives a high velocity before it enters the moving blades 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 expanded from a high pressure to a condenser pressure in one or more nozzles The steam is allowed to expand in the nozzle, where it gives a high velocity before it enters the moving blades The pressure and temperature of steam remains constant ANSWER DOWNLOAD EXAMIANS APP
Steam Boilers, Engines, Nozzles and Turbines The velocity of flue gases (V) through the chimney under a static draught of (H') metres is given by V = 2g/H' V = 2g H' V = H'/2g V = 2gH' V = 2g/H' V = 2g H' V = H'/2g V = 2gH' ANSWER DOWNLOAD EXAMIANS APP
