3. For each case, write the degrees of freedom (F) and specify
the state of the water. Calculate quality or degrees of superheat
whenever applicable.
a) What is the quality of wet steam if V= 8.35 cm3 /g at 10,703
kPa? What is the specific internal Energy? What is the specific
entropy?
b) What is the specific enthalpy of steam at T= 200°C and P=525
kPa?
c) What is the specific entropy of steam at 9100 kPa and 560°

An ideal gas with f = 3 degrees of freedom starts with a volume
of 6 liters, a pressure of 1.1×10^5 Pa and a temperature of 20◦C.
The gas is compressed adiabatically to 2 liters, then expands at
constant temperature back to 6 liters. Then it is again
adiabatically compressed to 2 liters, and isothermally expands to 6
liters.
Draw the 4 steps in a P −V diagram.
Calculate the final pressure and final temperature.

A heat engine made with an ideal gas with f = 5 degrees of
freedom has 3 steps. Starting with a volume of 8 liters and a
pressure of 1.3 × 10^5 Pa, the gas is compressed adiabatically to a
volume of 1 liter and a pressure P2. Next the gas expands at
constant pressure back to 8 liters, then the pressure drops at
constant volume back to 1.3×10^5 Pa. Draw the cycle in a P −V
diagram. Calculate the...
