Carbon monoxide in a piston-cylinder device is compressed from 1 bar and 37?C to 3 bar and 147?C. The compression process requires work input of 88 kJ/kg.
A power cycle operates between hot and cold reservoirs at 500K and 310K, respectively. At steady state the cycle develops a power outpoint of 0.1 MW.
Calculate the steady rate of entropy production, s& (kJ/K/s), by the power unit & by the refrigeration unit. Entropy production is not a good thing. Find the amount of unnecessary or lost power = TATM * s& (kW).
A cylinder/piston contains carbon dioxide at 1 MPa, 300oC with a volume of 200 L. The total external force acting on the piston is proportional to V3. The system is allowed to cool to room temperature, 20oC. What is the total entropy generation fo
