CHEGG Air flows through a compressor at a steady mass flow rate of 0.5 kg/s. The air enters the compressor at a velocity of 15 m/s, pressure of 101.3 kPa, and specific volume of 0.8m3 /kg. The air exits at a velocity of 10 m/s, pressure of 800 kPa, and specific volume of 0.15m3 /kg. The internal energy of the air is increased by 80 kJ/kg. (a) (8 pts) Drive an equation to calculate the required power starting from the full equation (eq. 1-24) of the law of conservation of energy and calculate the power required to drive the compressor, assuming there is no heat loss due to a cooling system. (b) (2 pts) Describe if

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.
