Steam Boilers, Engines, Nozzles and Turbines In a nozzle, the effect of super-saturation is to Increase the entropy Increase the heat drop Decrease dryness fraction of steam Decrease specific volume of steam Increase the entropy Increase the heat drop Decrease dryness fraction of steam Decrease specific volume of steam ANSWER DOWNLOAD EXAMIANS APP
Steam Boilers, Engines, Nozzles and Turbines There is always some steam left in the clearance space from the previous stroke. This steam left in the clearance space is called Wet steam Superheated steam Cushion steam Saturated steam Wet steam Superheated steam Cushion steam Saturated steam ANSWER DOWNLOAD EXAMIANS APP
Steam Boilers, Engines, Nozzles and Turbines The latent heat of steam at pressures greater than atmospheric in comparison to latent heat at atmospheric pressure is May be less or more depending on temperature Less Equal More May be less or more depending on temperature Less Equal More ANSWER DOWNLOAD EXAMIANS APP
Steam Boilers, Engines, Nozzles and Turbines In a reaction turbine 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 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 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 ANSWER DOWNLOAD EXAMIANS APP
