Unformatted text preview: wall of the bottle. The valve remains open during the process so that the trapped air also reaches mechanical equilibrium with the atmosphere. Determine the heat transfer through the wall of the bottle during this filling process. #4 (5-157) The air flow in a compressed air line is divided into two equal streams by a T-fitting in the line. The compressed air enters this 2.5 cm diameter fitting at 1.6 MPa and 40 C with a velocity of 50 m/sec. Each outlet has the same diameter as the inlet, and the air at these outlets has a pressure of 1.4 MPa and a temperature of 36 C. Determine the velocity of the air at the outlets and the rate of change of flow energy (flow power) across the T-fitting. #5 (6-9) Is it possible for a heat engine to operate without rejecting any waste heat to a low temperature reservoir? Explain. #6 (6-15) In the absence of any friction and other irreversibilities, can a heat engine have an efficiency of 100 percent? Explain....
