Question
Consider the mixing chamber shown in the figure below. In the device, 2.2 kg/s ammonia at
1000 kPa, 200°C is mixed with another flow of ammonia at 25°C and quality 40%. There is a
heat loss of 6 kJ/s to the ambient.
(a) If the outgoing ammonia is saturated vapor at 1000 kPa, find the volumetric flow rate of
the second flow.
(b) If the mixing chamber was insulated, what would be the phase of the ammonia exiting
the device? Explain.
