Question
Can u solve for me both problems I req to u kindly solve for me both accept my req thanks advance
Problem 5 (€
A power cycle operates between a reservoir at temperature T and a lower-temperature
reservoir at 280 K. At steady state, the cycle develops 40 kW of power while rejecting 1000
kJ/min of energy by heat transfer to the cold reservoir. Determine the minimum theoretical
value for T, in K.
Problem 6 (
An inventor claims to have developed a device that executes a power cycle while operating
between reservoirs at 900 and 300 K that has a thermal efficiency of (a) 70%, (b) 50%. Evaluate
the claim for each case.
