Following Electrical Engineering Multiple choice objective type questions and answers will help you in BSNL JTO, GATE 2024 and IES 2024 examinations :

1.The ratio of exit pressure to inlet pressure of maximum mass flow rate per area of steam through a nozzle when steam is initially superheated is

0.555
0.578
0.5457
0.6

2.For the induced draught the fan is located

near bottom of chimney
near bottom of furnace
at the top of the chimney
anywhere permissible

3.Artificial draught is produced by

air fans
steam jet
fan or steam jet
all of the above

4.The effect of considering friction losses in steam nozzle for the same pressure ratio leads to

increase in exit velocity from the nozzle
decrease in exit velocity from the nozzle
no change in exit velocity from the nozzle
increase or decrease depending upon the exit quality of steam

5.The draught produced, for a given height of the chimney and given mean temperature of chimney gases

decreases with increase in outside air temperature
increases with increase in outside air temperature
remains the same irrespective of outside air temperature
may increase or decrease with increase in outside air temperature
