Reheating in a gas turbine
-
In a single stage, single acting reciprocating air compressor, without clearance, the workdone on the air during isentropic compression is __________ the heat required to raise the temperature of air from T1 to T2 at a constant pressure.
-
Workdone by an air compressor __________ upon the way in which the air is compressed.
-
In a compressor, work is done on the piston during suction of air and work is done by the piston during compression as well as delivery of air.
