Q3: 1.15103kg/h steam (H=2676kJ/kg) enters an adiabatic blender with another stream of steam at 400C(H=3278kJ/kg,V=0.00311cm3/g). If the outlet stream leave at 300C (H=3074kJ/kg). If all streams are operated at atmospheric pressure, estimate the mass flowrate of the mixed stream and the volumetric flowrate of the unknown inlet stream of 400C. Q4: Carbon dioxide gas enters a water-cooled compressor at conditions P1=1 bar and T1= 10C, and is discharged at conditions P2=36 bar and T2=90C. The entering CO2 flows through a 10cm-diameter pipe with an average velocity of 10m/s and is discharged through a 3cm-diameter pipe. The power supplied to the compressor is 12.5kJmol1. What is the heat-transfer rate from the compressor? H1=21.71kJmol1H2=23.78kJmol1V1=23.40Lmol1V2=0.7587Lmol1 Q5: Consider 50ft3/min ideal gas (Cp=0.2485Btu/lbm.R ) is passing through a well-insulated expander. If the stream is fed at 500 psia and 800F stream and exits at 60 psia and 250F. If the volume flow rate of the air at the outlet conditions is 50ft3/min, determine the generated rate of energy (kW)
