2.1 Taking the recent World Energy Council and United Nations resource-base figures forthe total amount of fossil energy in the ground worldwide as 356,000 quads, how longwill it take to exhaust our fossil resources, assuming that we can recover one-half of theresource base and that usage grows at 3% per year? The world currently consumes about400 quads of primary energy per year, of which 85% is from fossil sources. (Hint: youwill need to account for the compounding, exponential growth effect of the 3% per yearincrease in consumption.)
A fluid enters an apparatus at 480 ft/s, initially the pressureof the fluid is 120 psia, the specific volume of 5ft3/lb andthe internal energy is 383 BTU/lb. The fluid leaves theapparatus at 25psia, specific volume of 18 ft3/lb, an exitvelocity of 1200 ft/s and internal energy of 120 BTU/lb. Theheat radiation loss is 10 BTU/lb.

A closed, rigid tank contains 4 kg of air initially at 300 K, 1 bar. As illustrated in the figure below, the tank is in contact with a thermal reservoir at 600 K and heat transfer occurs at the boundary where the temperature is 600 K. A stirring rod transfers W = -480 kJ of energy as shown in the diagram.The final temperature is 600 K. The air can be modeled as an ideal gas with cν = 0.733 kJ/kg · K and kinetic and potential energy effects are negligible. Determine the amount of entropy transferred into the air and the amount of entropy produced, each in kJ/K. Q/Tb = kJ/K σ = kJ/K

Helium in a piston/cylinder at 70 F, 20 psia is brought to 720 R in a reversible polytropic process with exponent n = 1.25. Find the final pressure and both the specific heat transfer and the specific work.
Helium is contained in a balloon at 0.5 m3, 100 °C inside an evacuated, insulated chamber. The balloon is suddenly punctured, allowing the helium to expand into the chamber with a volume of 5 m3. Treat the helium as an ideal gas. How much entropy is generated per kg of helium? Why does this process generate entropy?
From a state defined by 285.3 psig, 100ft3 and 240F, helium (R=386.04 ft-lbf/lbm-R, k=1.666) undergoes an isentropic process to 0.3psig. What is the change in internal energy? (BTU)
So my chosen refrigerant is R-32. I'm having trouble finding a good range of pressure and temperature that takes the isentropic efficiency into account. I was using the software,EES, as my source of property retrieval since I couldn't find properties of R-32 anywhere else.
