7. If 10 kg/min of air are compressed isothermally from p, 96 kPa and V, = 7.65 m/min to p, = 620 kPa, find the work, the change of entropy and the heat for (a) nonflow process and (b) a steady flow process with v, = 15 m/s and v, = 60 m/s. Ans. (a)-1370KJ/min,-5.356 kJ/K.min; (b)-1386.9kJ/ %3D min
