Question

(45 pes) An inventor claims to have developed a steady flow device that operates on an electrical power input of 250 kW, has one inlet and two outlets. A stream of ammonia e device at 100 kPa and 20PC at a rate of 1 kg/s. The two exiting streams ow rate, one is at 200 kPa, 20°C and the other is a saturated liquid at 10 aims that heat transfer occurs with an uniform surface temperature sume that kinetic and equal mass of 25 C. Is this possible? potential energy effects are negligible. Use the first and second law of rmodynamics to demonstrate your answer.
