Two air streams are combined in a continuously operated heater. The first stream (stream 1) has a molar flow rate of 9.9 mol/s. The flow of the second stream (stream 2) is unknown but its temperature is 32 C and it has a gauge pressure of 31kPa. The outlet air stream from the heater is at 225C, a gauge pressure of 12 kPa and flows at 1610 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
