A thermodynamic system with 45 pounds of Neon simultaneously reject heat and receive paddle-work input. The fluid is stored in a vessel having an initial temperature of 450 deg F to a final temperature of 110 deg F. If the heat is five times the paddle work in constant pressure process, determine (a) the change in internal energy, (b) change in enthalpy, (c) change in entropy, (d) Heat, (e) Paddle work, and (f) Net work. Consider k = 1.667 and Cv = 0.15 BTU/lbm-R.

Basic Thermodynamic Processes

The word 'thermodynamics' can be divided into two words, 'thermo' and 'dynamics'. The word thermo deals with the heat and thermal phenomenon, whereas dynamics deals with forces or external agent that drives the heat flow or aids in the motion of heat.
