ME 322 – Mechanical Engineering Thermodynamics
Spring 2016
Homework #5
READING QUESTIONS
1) What are the variables (symbol), SI units, English units and fundamental MLt dimensions
associated with the following thermodynamic quantities: isobaric coefficient of volume
expansion, isothermal coefficient of compressibility, internal energy, specific internal
energy, enthalpy, specific enthalpy, isochoric heat capacity, isobaric heat capacity?
2) What assumptions and procedures are used to determine thermodynamic properties of
incompressible materials?
3) What assumptions and procedures are used to determine thermodynamic properties of
ideal gases with constant heat capacities?
4) What assumptions and procedures are used to determine thermodynamic properties of
ideal gases with variable specific heats?
5) What are two examples of non-ideal gas equations of state? What parameters are needed
to use these equations and what are the units associated with each of these parameters?
What phenomena do these parameters incorporate that are not represented in the ideal gas
equation of state?
PROBLEMS
Solve the following problems 3.8, 3.12, 3.15, and 3.18 from the Balmer book. In conjunction
with 3.18 show two isotherms below the critical temperature, one isotherm at the critical
temperature, and one isotherm above the critical temperature on a P-v diagram.
Homework is due at the beginning of the next class period, unless specified otherwise
on the course website. Homework not handed in at the beginning of the class period is
late and will not be graded.
