A heat engine cycle is executed with steam in the saturation dome. The pressure of steam is 1.1 MPa during heat addition and 0.3
klio [65]

Answer:The highest possible efficiency of this heat engine is 11%

Explanation:

Saturated water temperature at  P1, Pressure in Heat addition,

1.1 MPa=185°C +273= 458K

Saturated water temperature at  P2, Pressure in Heat rejection,

0.3MPa=133.5°C+ 273=406.5K

The highest possible efficiency of any heat engine is the Carnot efficiency given as

Carnot efficiency,  ηmax = 1- (T2/ T1)

1- (406.5K/458K)

1-0.88755=0.112

=11%
