An inventor claims to have developed a device which requires no energy transfer by work or heat transfer, yet able to produce hot and cold stream of air from a single stream of air at an intermediate temperature of 21°C and a pressure of 5.2 bar, separate streams of air exit at a temperature of 1 bar. Sixty percent of mass entering the device exists at the lower temperature. Evaluate the inventor’s claim, assuming ideal gas as working fluid and neglecting changes in kinetic and potential energy.
