ENGINEERING
A piston–cylinder device contains 4 kg of argon at 250 kPa and 35$^ { \circ } \mathrm { C }$. During a quasi-equilibrium, isothermal expansion process, 15 kJ of boundary work is done by the system, and 3 kJ of paddle-wheel work is done on the system. Determine the heat transfer for this process.
ENGINEERING
Air from a line at 1800 lbf/in.2, 60 F flows into a 20-ft3 rigid tank that initially contained air at ambient conditions, 14.7 lbf/in.2, 60 F. The process occurs rapidly and is essentially adiabatic. The valve is closed when the pressure inside reaches some value, P2. The tank eventually cools to room temperature, at which time the pressure inside is 750 lbf/in.2. What is the pressure P2? What is the net entropy change for the overall process?
ENGINEERING
A sheet-metal box in the shape of a 0.70-m cube has a surface emissivity of 0.7. The box encloses electronic equipment that dissipates 1200 W of energy. If the surroundings are taken to be black at 280 K, and the top and sides of the box are considered to radiate uniformly, what will be the temperature of the box surface?
