Question

The steam supply to an engine comprises two streams which mix before entering the engine. one stream is supplied at the rate of 0.01 kg/s with an enthalpy of 2952 kj/kg and a velocity of 20 m/s. the other stream is supplied at the rate of 0.1 kg/s with an enthalpy of 2569 kj/kg and a velocity of 120 m/s. at the exit from the engine the fluid leaves as two streams, one of water at the rate of 0.001 kg/s with an enthalpy of 420 kj/kg and the other of steam; the fluid velocities at the exit are negligible. the engine develops a shaft power of 25 kw. the heat transfer is negligible. evaluate the enthalpy of the second exit stream.

Answer 1

Answer:

enthalpy of the second exit tream2402 kj/kg.
