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 Induced draught Natural draught Forced draught Balanced draught Induced draught Natural draught Forced draught 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 Two times the height of chimney One-half the height of chimney Four times the height of chimney Equal to the height of chimney Two times the height of chimney One-half the height of chimney Four times the height of chimney ANSWER DOWNLOAD EXAMIANS APP
Steam Boilers, Engines, Nozzles and Turbines The theoretical indicator diagram of a simple steam engine is based upon the assumption that The expansion (or compression) of the steam is hyperbolic Steam is admitted at boiler pressure and exhausted at condenser pressure All of these There is no pressure drop due to condensation The expansion (or compression) of the steam is hyperbolic Steam is admitted at boiler pressure and exhausted at condenser pressure All of these There is no pressure drop due to condensation ANSWER DOWNLOAD EXAMIANS APP
Steam Boilers, Engines, Nozzles and Turbines The clearance in the engine cylinder Increases the mean effective pressure Increases the workdone All of these Decreases the efficiency of the engine Increases the mean effective pressure Increases the workdone All of these Decreases the efficiency of the engine ANSWER DOWNLOAD EXAMIANS APP
