The internal energy of a perfect gas is a function of the absolute temperature only B. No Heat Engine can be more efficient than a Reversible Heat Engine operating between the same temperature limits C. A pure crystalline substance at absolute zero temperature is in perfect order, and its entropy is zero D. When a system undergoes a complete cycle, the net Heat supplied plus the net Work input is zero. E. It is impossible for a heat engine to produce a net work output in a complete cycle if it exchanges heat only with a single energy reservoir. F. It is impossible to construct a device that operating in a cycle will produce no effect other than the transfer of heat from a cooler to a hotter body.

Please show system sketches and related energy flows for all problems. 1.a) Determine the electrical power supplied to a boiler when the temperature of the entering water is 20 C and the exiting temperature is 89 C. The flow of.the pressured water is 2 Kg/s. There is a negligible pressure drop through this boiler and it operates at a constant pressure of 3 bars. The specific heat is c = 4,370 J/(Kg K). There is a 1.5(105 ) W rate of heat loss from the boiler during this process to a surrounding at 293.2 k. Consider steady state conditions. 1.b) Calculate the total rate of entropy production 1.c) Calculate the total rate of exergy destruction (W). Given the dead state temperature 293.2 K and pressure 1 bar.

The beating of the human heart can be modeled by a thermodynamic cycle. In this chapter, we have used PV diagrams to show processes occurring for a gas. Such diagrams can also be used for a liquid, such as blood in the heart. The figure below shows an idealized cycle for the left ventricle (LV) during a single beat of the heart. P(mm Hg) 120 78.0 20.0 10.0 A V (mL) 44.0 149 The cycle begins at point A with the opening of the mitral valve, which fills the LV with blood from the left atrium. During this process, the pressure and volume of the blood in the ventricle increase linearly until the mitral valve closes at point B. At that point, the muscles surrounding the LV contract, increasing the pressure of the blood. Because both the mitral and the aortic valves are closed, and because blood is essentially incompressible, the process is isovolumetric. The pressure increases to the diastolic pressure of 78.0 mm Hg (1 mm Hg = 133.322 Pa) at point C. Now, the aortic valve opens, pumping the…
