A heat engine is supplied with 278 kW of heat at a constant fixed temperature of 283°C and the heat rejection takes place at 5°C. The engine is reversible if the heat rejected, in kW, is

Validate

Solution:

For reversible heat engine efficiency

x=1-T_R/T_S=1-278/556=0.5

x=W/Q_S=1-Q_R/Q_S

Q_R=139
