Extracted text: A system executes a power cycle while receiving 1000 Btu by heat transfer at a temperature of 900°R and discharging 600 Btu by heat transfer at a temperature of 540°R. There are no other heat transfers. Determine the cycle thermal efficiency. Use the Clausius Inequality to determine ocvcle, in Btu/°R. Determine if this cycle is internally reversible, irreversible, or impossible.
