Question: A jet-ejector pump, shown schematically in Fig P9.90, is a device in which a low-pressure (secondary) fluid is compressed by entrainment in a high-velocity (primary)

A jet-ejector pump, shown schematically in Fig P9.90, is a device in which a low-pressure (secondary) fluid is compressed by entrainment in a high-velocity (primary) fluid stream. The compression results from the deceleration in a diffuser. For purposes of analysis this can be considered as equivalent to the turbine-compressor unit shown in Fig P9.82 with the states 1, 3, and 5 corresponding to those in Fig. P9.90. Consider a steam jet-pump with state 1 as saturated vapor at 35 kPa; state 3 is 300 kPa, 150C; and the discharge pressure, P5, is 100 kPa.
a. Calculate the ideal mass flow ratio, m1/m3.
b. The efficiency of a jet pump is defined as = (m1/m3) actual / (m1/m3) ideal for the same inlet conditions and discharge pressure. Determine the discharge temperature of the jet pump if its efficiency is 10%.
