One British thermal unit will raise the temperature of _____ 1b of water _____F.
A piston-cylinder contains nitrogen initially at 100 kPa, 20°C, and a volume of 0.283 m³ (State 1). The nitrogen undergoes two processes. First, the nitrogen is compressed to 7000 kPa (State 2) in an isothermal process. Finally, the nitrogen is expanded to 100 kPa (State 3) in a reversible adiabatic process. You may assume that nitrogen is an ideal gas with constant (average) specific heats: Cp = 1.039 kJ/kgK, c, = 0.742 kJ/kgK, and R= 0.297 kJ/kgK.
