Question

Oxygen enters an insulated 12-cm-diameter pipe with a velocity of 70 m/s. at the pipe entrance, the oxygen is at 240 kpa and 20 c; and, at the exit, it is at 200 kpa and 18

c. calculate the rate at which entropy is generated in the pipe

Answer 1

Oxygen enters an insulated 12-cm-diameter pipewith a velocity of 70 m/s. At the pipe entrance, the oxygen is at 240kPa and 20°C; and, at the exit, it is at 200kPa and 18°C ...
