ME 3513 – Thermodynamics I Solutions to Homework # 3 – Properties of a pure substance II 1. A cylinder fitted with a frictionless piston contains butane at 25 ° C, 500 kPa. Can the butane reasonably be assumed to behave as an ideal gas at this state ? 2. A spherical helium balloon of 10 m in diameter is at ambient T and P, 15oC and 100 kPa. How much helium does it contain? It can lift a total mass that equals the mass of displaced atmospheric air. How much mass of the balloon fabric and cage can then be

Unformatted text preview: lifted? 3. A 1 m3 rigid tank has propane at 100 kPa, 300 K and connected by a valve to another tank of 0.5 m3 with propane at 250 kPa, 400 K. The valve is opened and the two tanks come to a uniform state at 325 K. What is the final pressure? 4. What is the percent error in specific volume if the ideal gas model is used to represent the behavior of superheated ammonia at 40 C, 500 kPa? What if the generalized compressibility chart, Fig. D.1, is used instead?...
