Question

a system executes a power cycle

while receiving 750 kJ by heat transfer at a temperature of

1500 K and discharging 100 kJ by heat transfer at a temperature

of 500 K. Another heat transfer from the system occurs at a

temperature of 1000 K. Using Eq. 5.13, determine the thermal

(d) 0.35 kJ/K.

a system executes a power cycle while receiving 750 kJ by heat transfer at a temperature of 1500 K and discharging 100 kJ by heat transfer at a temperature of 500 K. Another heat transfer from the system occurs at a temperature of 1000 K. Using Eq. 5.13, determine the thermal efficiency if sigma cycle is 0 kJ/K, 0.1 kJ/K, 0.2 kJ/K, 0.35 kJ/K.
