An open system is one in which
-
One reversible heat engine operates between 1600 K and T2 K and another reversible heat engine operates between T2 K and 400 K. If both the engines have the same heat input and output, then temperature T2 is equal to800K
-
The efficiency of a gas turbine is given by
-
When the gas is heated at constant volume, the heat supplied
-
In closed cycle gas turbine, the air is compressed

heat and work crosses the boundary of the system, but the mass of the working substance does not crosses the boundary of the system |
|
B.
mass of the working substance crosses the boundary of the system but the heat and work does not crosses the boundary of the system |
|
C.
both the heat and work as well as mass of the working substance crosses the boundary of the system |
|
D.
neither the heat and work nor the mass of the working substance crosses the boundary of the system |
