PROBLEM #1.
Air is compressed in an adiabatic piston-cylinder device from 220C and 95 kPa in a reversible manner. If the
compression ratio V1/V2 is 8, determine the final temperature of the air.
PROBLEM #2.
An internally reversible refrigerator is

PROBLEM #1:
A cylinder having an initial volume of 2-m3, contains steam at 10 bars and 200oC [State 1]. The
cylinder is cooled at constant temperature until the volume is 56.4% of the initial volume
[State 2]. The constant temperature process is fo

TEST 2
PROBLEM # 1:
Air enters a compressor operating at steady state at a pressure of 1 bar, a temperature of
17oC, and a velocity of 6 m/s through an inlet with an area of 0.1 m 2. At the exit, the
pressure is 7x102 kPa, the temperature is 450 K, and th
