Questions 13 and 14 are to be solved using Generalized Charts. Both problems involve helium, which has the following physical properties: cP0RTcrPcr=5.19kJ/kgK(assumedconstant)=2.08kJ/kgK=5.3K=230kPa 13. Helium is compressed adiabatically in a steady-flow compressor from 4.24K and 92kPa (Stream 1) to 10.6K and 1840kPa (Stream 2). Determine the work input to the compressor per kg of helium (in kJ/kg ). 14. Two kg of helium is contained in a volume of 0.3m3 at a temperature of 3.71K. What is the quality of the helium?
