Consider a steady state device in which a stream of ammonia enters at 100 kpa, 50◦c, at a rate of 1 kg/s. two streams exit the device at equal mass flow rates: one at 200 kpa, 50◦c, and the other is saturated liquid at 10◦c. it is claimed that the device operates in a room at 25◦c with an electric power input of 250 kw. is this possible

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

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.

Different types of steels contain different elements that alter the characteristics of the steel. for each of the following elements, explain what the element does when alloyed with steel.
