What the Answer?

A stream of air at 35.0C and a gauge pressure of 0.400atm(5 tream 1) flows into a pipe passing through a heater, emerges at 77.0C and 0.200atm (gauge), and splits into two streams. Stream 2 passes out of the system, and Stream 3 goes through another heater and emerges at 160.0C and 0.050 atm (gauge). Flowmeters mounted in streams 1 and 2 show readings of 3120L/min and 1940L/min respectively. What should the flowmeter for Stream 3 read after the stream emerges from the heater
