There are 1.36 kgm of air at 137.9 Kpaa stirred with internal paddles in an insulated rigid container whose volume is 0.142 m3, until the pressure becomes 689.5 Kpaa. Determine (a) the work input, (b) Δ(pV), and (c) Q. Cp=1.0062 kj/(Kgm.°K), Cv = 0.7186 kj/(Kgm.°K...

While the pressure remains constant at 689.5 kpaa the volume of a system of air changes from 0.567 m3 to 0.2283 m3. Determine (a) ΔU, (b) ΔH, (c) Q, (d) ΔS. (e) If the process is nonflow and internally reversible, what is the work? Cp = 0.24Btu/(lbm.° R), Cv...
