Two air streams are combined in a continuously operated heater. The first stream (stream 1) has a molar flow rate of 50.2 mol/s. The flow of the second stream (stream 2) is unknown but its temperature is 44 and it has a gauge pressure of 32kPa. The outlet air stream from the heater is at 150, a gauge pressure of 8 kPa and flows at 9970 standard cubic meters per hour. Assume air has an average molar mass of 29, and atmospheric pressure is 1 standard atmosphere and determine the:

a) absolute pressure of stream 2 in kPa

b) molar flow rate of stream 2 in mol/s

c) mass flow rate of stream 2 in kg/hr

d) actual volumetric flow of stream 2 in m³/hr

e) standard volumetric flow of stream 2 in m³/hr
