A chemical plant requires large quantities of steam of low quality (approximately 10%) at 175°C. High-pressure boilers are quite expensive. An inventor suggests that saturated atmospheric pressure steam (cheap boiler) could be mixed with high-pressure water (7 MPa and 17°C) in an adiabatic steady fl ow process to produce the desired feed water. The inventor claims that the requirements could be satisfied by mixing two parts (by mass) of water with one part of steam. a. Are the inventor’s fi gures reasonable in view of the fi rst law? b. Is the process thermodynamically possible in view of the second law? Support your answer with proper calculations
