Question

**Thermodynamics System Analysis**

Consider a piston-cylinder device containing \( m = 1 \, \text{kg} \) of air at the initial temperature \( T_1 = 900 \, \text{K} \) and pressure \( P_1 = 895 \, \text{kPa} \) (state 1). The ambient temperature and pressure are maintained at \( T^{(e)} = 300 \, \text{K} \) and \( P^{(e)} = 100 \, \text{kPa} \). The air expands in a reversible adiabatic process until the air pressure reaches the ambient pressure \( P^{(e)} \) (the intermediate state 2). Subsequently, the system undergoes an isobaric process until it reaches the dead state DS.

**Explanation of Processes:**

1. **Reversible Adiabatic Process:**
- The system expands without heat transfer.
- During this process, the work done by the system results in a decrease in internal energy, causing the temperature to drop until the pressure equals the ambient pressure \( P^{(e)} \).

2. **Isobaric Process:**
- The pressure remains constant as the system continues to change until reaching the dead state.
- The system exchanges heat with the surroundings to reach equilibrium at the ambient temperature.

2. Electrical components often failure due to thermal overload. It follows that thermal analysis of electrical components is critical to their longevity. Consider a silicon chip which is sitting atop a ceramic substrate with 35 mm2 of exposed surface area. Operating at steady state, the chip can pull up to 120 mW of power. The chip surface is cooled by convection from flowing air at 20°C. The heat transfer from the chip to the air is given by Q = hA(T, – T) where h is the thermal convection coefficient, A is the exposed surface area, and Tb and Tr are absolute temperatures of the body and coolant fluid, respectively. h of the flowing air is found to be 250 W/(m2-K). Assuming heat transfer to the substrate is negligible compared to convection, determine: the heat transfer occurring at steady state (W) the temperature at the outer surface of the chip ("C) a. b.

2. A heat pump is like a refrigerator in that it uses work to take heat from a cold source (Tc, the inside of a house) and dumps it into a hot source (Th, usually the outdoor environment). a) Use the second law to find the magnitude of the work |w| needed to extract |qc] from the cold source and dump into the hot source. b) Assume all processes are reversible and the second law to explain why |w| > 0 if lgc] > 0 in part a).
If steam flows through a nozzle at steady-state, entering the nozzle with a pressure of 0.5 MPa and a temperature of 673 K, where H = 3272 kJ/kg, and exiting at 0.1 MPa and 623 K, where H = 3176 kJ/kg, what is its exiting velocity (in m/s)? Assume that the heat loss is 10% of the change in kinetic energy.
The manufacturer of the device claims that it accepts a heat transfer at a rate of QH = 3.0 kW from a low-grade source of geothermal heat at TH = 80ºC and rejects heat at rate QC to the atmosphere at TC = 20ºC. The device operates at steady state and produced work at a rate of W= 2.5 kW. There are no other heat or work transfers from the device. a.) What is the rate at which the device rejects heat to the atmosphere, QC ? b.) Is this device possible? Justify your answer using an entropy balance.
