Steam Boilers, Engines, Nozzles and Turbines The effect of super-saturation is that the Entropy and specific volume of the steam increases Exit velocity of steam reduces All of these Mass of the steam discharged increases Entropy and specific volume of the steam increases Exit velocity of steam reduces All of these Mass of the steam discharged increases ANSWER DOWNLOAD EXAMIANS APP
Steam Boilers, Engines, Nozzles and Turbines A device used to increase the temperature of saturated steam without raising its pressure, is called Superheater Fusible plug Blow off cock Stop valve Superheater Fusible plug Blow off cock Stop valve ANSWER DOWNLOAD EXAMIANS APP
Steam Boilers, Engines, Nozzles and Turbines For maximum discharge through a chimney, the condition is that height of hot gas column producing the draught should be Equal to the height of chimney One-half the height of chimney Two times the height of chimney Four times the height of chimney Equal to the height of chimney One-half the height of chimney Two times the height of chimney Four times the height of chimney ANSWER DOWNLOAD EXAMIANS APP
Steam Boilers, Engines, Nozzles and Turbines If the critical pressure ratio for steam is 0.546, then the steam is initially Dry saturated steam None of these Wet steam Superheated steam Dry saturated steam None of these Wet steam Superheated steam ANSWER DOWNLOAD EXAMIANS APP

Steam Boilers, Engines, Nozzles and Turbines The air pressure at the fuel bed is reduced below that of atmosphere by means of a fan placed at or near the bottom of the chimney to produce a draught. Such a draught is called Balanced draught Natural draught Forced draught Induced draught Balanced draught Natural draught Forced draught Induced draught ANSWER DOWNLOAD EXAMIANS APP
