1.2 2 2.50 WP A gas undergoes a process in a piston-cylinder assembly during which the pressure-specific volume relation is pul2 = con- stant. The mass of the gas is 0.4 lb and the following data are known: P₁ = 160 lbf/in.², V₁ = 1 ft³, and p₂ = 390 lbf/in. During the process, heat transfer from the gas is 2.1 Blu. Kinetic and potential energy ef- fects are negligible. Determine the change in specific internal energy of the gas, in Btu/lb.
As shown on the right, a vertical piston–cylinder assembly containing a gas is placed on a hot plate. The piston initially rests on the stops. With the onset of heating, the gas pressure increases. At what pressure, in bar, does the piston start rising? The piston moves smoothly in the cylinder and g = 9.81 m/s2.

1. As seen in Fig P1.2 from the textbook, water circulates through household piping to be used by multiple appliances. For each labeled device (water heater, dishwasher, shower, and water meter), draw a schematic. Identify a system boundary, noting where the system interacts with its surroundings (i.e. where mass and/or energy enter and leave the system).

A gas is confined in a cylinder with a diameter of 1.25 ft by a piston, on which a counterweight rests. Together, the piston and the counterweight have a mass of 250 lbm. The local gravitational acceleration is 32.169 ft/s^2, and the atmospheric pressure is 30.12 in Hg. a. What is the force in (lbf) exerted on the gas by the atmosphere, piston, and counterweight, assuming there is no friction between the piston and the cylinder? Answer: F = 2,864.2 lbf. b. What is the gas pressure in (psia)? Answer: Pabs = 16.208 psia. c. If the gas in the cylinder is heated, it expands, pushing the piston and counterweight upward. If the piston and counterweight are lifted by 1.7 ft, what is the work done by the gas in (ft-lbf)? What is the change in potential energy of the piston and counterweight? Answer: w = 4,869.1 ft-lbf, and ΔEp = 424.9 ft-lbf. traduza para o inglês: Um gás é confinado em um cilindro com 1,25 (ft) de diâmetro por um êmbolo, sobre o qual…
A closed system consisting of 10 lb of air undergoes a polytropic process from p₁-70 lbf/in², v₁-4 ft³/lb to a final state where p2 - 20 Ibf/in², v₂-12 ft³/lb.

2.23 WP A gas contained within a piston-cylinder assembly under- goes three processes in scries: Process 1-2: Constant volume from p = 1 bar, V₁ = 4 m³ to state 2, where p₂ = 2 bar. Process 2-3: Compression to V₁ = 2 m³, during which the pres- sure-volume relationship is pV = constant. Process 3-4: Constant pressure to state 4, where V₁ = 1 m³. Sketch the processes in series on p-V coordinates and evaluate the work for cach process, in kJ.
