Overview
Need help with my Physics question - I’m studying for my class.
Air in an insulated piston cylinder is initially at 300K and 100 kPa. The air is allowed to expand isentropically until the air's specific volume reaches 2.0 m
3
/kg. How much work per mass (kJ/kg) is produced during the expansion? Use the IG model (variable specific heat) to calculate the answer.
a) 156.6 kJ/kg
b) 61.4 kJ/kg
c) 32.3 kJ/kg
d) -32.3 kJ/kg
