(a) To determine The performance of the system using the Clausius statement of second law. Explanation The performance of the system is analyzed by the proof of Clausius statement. If Clausius statement obeys then equivalence exits, else system is not possible. The statement of Clausius, It is impossible to construct a device that operates in a cycle and produces no net effect apart from transferring heat from one reservoir at lower temperature to the other at higher temperature. Consider a combined system of given system with heat pump at steady state such that the work output from the system is fed to the heat pump. The Figure-(1) shows the combined system arrangement. Figure-(1) Here, the heat transfer from the cold reservoir to heat pump is Q C ′ , the heat transfer from the and heat transfer from the heat pump to the hot reservoir is Q H ′ . Write the expression for the energy balance. Q H + Q H ′ = Q C + Q C ′ (I) Here, the heat transfer from the cold reservoir to the system is Q C and the heat transfer from the hot reservoir to the system is Q H . Substitute 500 kJ for Q C and 400 kJ for Q H in Equation (I) (b) To determine The performance of the system using the Kelvin Plank’s statement of the second law.

A flat-plate solar collector is used to heat water by having water flow through tubes attached at the back of the thin solar absorber plate. The absorber plate has emmisssivity and an absorptivity of 0.9. The top surface where x=0 temp of the absorber is T0=35 degrees C, and solar radiation is incident on the basorber at 500 W/m^2 with a surrounding temp of 0 degrees C. The convection heat transfer coefficient at the absorber surface is 5 W/m^2 K, while the ambient temp is 25 degrees C. Show that the variation of the temp in the basorber plate can be expressed as T(x)=-(q0/k)x+T0, and determine net heat flux, q, absorbed by solar collector.

Using properties of a saturated water, explain how you would determine the mole fraction of water vapor at the surface of a lake when the temp of the lake surface and the atmospheric pressure are specified.

Consider a glass of water in a room at 15 degrees C and 97 kPa. If the relative humidity in the room is 100 percent and the water and the air are in thermal and phase equilibrium, determine the mole fraction of the water vapor in the air and the mole fraction of air in the water.
