induced steam jet draught

chimney draught

forced steam jet draught

none of these

The factor of evaporation for all boilers is always greater than unity.

The amount of water evaporated in kg per kg of fuel burnt is called equivalent evaporation from and at 100 Degree Centigrade.

The ratio of heat actually used in producing the steam to the heat liberated in the furnace is called boiler efficiency.

none of these

piston rod

connecting rod

eccentric rod

valve rod

equal power developed in each cylinder for uniform turning moment

equal initial piston loads on all pistons for obtaining same size of piston rod, connecting rod etc. for all cylinders

equal temperature drop in each cylinder for economy of steam

all of the above

to guide motion of the piston rod and to prevent it from bending

to transfer motion from the piston to the cross head

to convert heat energy of the steam into mechanical work

to exhust steam from the cylinder at proper moment
