5.A heat pump heats a house in the winter and then reverses to cool it in summer. The interior temperature should be 20-C in the winter and 25-C in the summer. Heat transfer through the walls and ceilings is estimated to be 2400 kJ per hour per degree temperature difference between the inside and outside. a. If the outside winter temperature is 0-C, what is the minimum power required to drive the heat pump? b. For the same power as in part (a),what is the maximum outside summer temperature for which the house can be maintained at 25-C?

2: The first law of thermodynamics can be written as: TdS = dU + PdV = dU = TdS – PdV. Moreover, we also use some other thermodynamic potentials. Most common three are: Helmholtz free energy: F = U – TS, Gibbs free energy: G = F + PV, Enthalpy: H = U + PV. From here prove the following: dF = -SdT – PdV, dG = -SdT +VdP, %3D dH = TdS + VdP. %3D
Thermodynamics: Assume temperature t1, quality x1, and alpha(i.e chose your own values).

STEP 2 Your first customer asked for an air piston-cylinder to use it in air compressors for generating high pressure. Your role in your company is to analyze, describe the operation of the system and their properties, explain and demonstrate the application of the first law of themodynamics to this system, as well as, illustrate the importance of expressions for work done in the system through the application of the first law. Describe the operation of the themodynamic system in Figure 1 and its properties, by constructing a P-V and T-V plots showing the process, the path, and the states then show the work under the curve on the P-V plot. STEP 3 Explain the application of the first law of thermodynamics to the system and explain the system parameters in terms of energy forms changes using the non-flow energy equation (NFEE) for the system and how they affect other parameters such as the final air temperature, by stating the appropriate assumptions and writing the general formula and…
