An ideal gas contained in a piston-and-cylinder device undergoes a thermodynamic cycle made up of three quasi-equilibrium processes.
Step 1-2: Adiabatic compression from 330 K and 9.35 atm to 12.58 atm
Step 2-3: Isobaric cooling
Step 3-1: Isothermal expansion
c.) Calculate Q, W, ΔU and ΔH, in J/mole,
for each step in the process and for the entire cycle. Assume that CP = (5/2) R.
d.) Is this cycle a power cycle or a refrigeration cycle? Explain. Calculate the thermal efficiency or COP of the cycle, whichever is appropriate.
A p-V diagram of hypothetical thermodynamic cycle with 1.24 mol of Ne (assume perfect gas) as the thermodynamic fluid initially at 330.15 K and 20.0 atm shown in the graph. Note, Cv,m = 1.5 R, Cp,m = 12 J K/mol
Determine q, w, and dS for each process in the cycle and for the whole cycle.
If this thermodynamical cycle is used as basis for a heat engine, what would be its efficiency? Use |w| / |q| formula.
A rigid, well-insulated tank contains air. A partition in the tank separates 12 ft^3 of air at 14.7 lbf/in2, 40◦F (left side of the tank) from 10 ft^3 of air at 50 lbf/in2, 200◦F(right side of the tank), as illustrated in the figure. The partition is removed and air from the two sides mix until a final equilibrium state is attained. The air can be modeled as an ideal gas, and kinetic and potential energy effects can be neglected. (Note: values for the left side of the tank are denoted with a subscript L, and values for the right side of the tank are denoted with a subscript R).
a) Determine the final temperature (in F)
b) Determine the final pressure (in lbf/in^2)
c) Calculate the amount of entropy produced, in Btu/R
d) Is this mixing process reversible or irreversible?
