![Q 2
Helium (He) is compressed in an adiabatic compressor from an initial state of 0.9653 bar
and 10°C to a final temperature of 160°C as shown in Figure Q 2. Sketch the actual and
ideal compression processes on T-s diagram and determine the compressor pressure ratio
and ideal specific work input if the reversible adiabatic or isentropic efficiency of the
compressor is 89%. Take, for helium, M = 4.003 kg/kmol and Cp = 5.1926 kJ/(kg-K).
[Hint: Use the concepts of steady-flow energy equation, SFEE, and the isentropic effi-
ciency. See Portal materials for combined Weeks 15 and Week 16.].
