I do not understand the chapter in general. May you please explain why you completed each step as you have. Thank you.
where do thet get the enthropy valvue for S2?
A condenser (heat exchanger) brings 1 kg/s water flow at 10 kPa quality 95% to saturated liquid at 10 kPa. The cooling is done by lake water at 20 degree Celsius that returns to the lake at 30 degree Celsius. For an insulated condenser, find the flow rate of cooling water.
4. An evaporator has R-410A at -20°C and quality 80% flowing in. The exit flow is saturated vapor at -20°C. a. Consider the heating to be a reversible process and find the specific heat transfer from the entropy balance. (Answer: 48.7 kJ/kg) b. If the heat source was at -10°C and the inlet and outlet streams still have the same properties as in a), calculate the specific entropy generation? (Answer: 7.33 J/(kg K))

A reciprocating air compressor taken in 2m3/min air at 0.11MPa, 293K which it delivers at 1.5 Mpa, 384 K to an after cooler where the air where the air is cooled at constant pressure to 298 K. the power absorbed by the compressor is 4.15 kW. Determine the heat transfer in (i) the compressor (ii) the cooler. State your assumptions.
I need help on the following question: The vapour compression cycle (picture provided), utilises the refrigerant R134a flowing at 0.05 kg s-1. Assuming that the compression is adiabatic and reversible. If the actual input power to the compressor is 2 kW, then: 1. You need to determine the theoretical input power to the compressor and the heat transfer (Φ) to theevaporator. Take the enthalpies h1, h2, and h3 to be 238.41, 263.68 and 81.5 kJ kg-1 (use the 'NH3 Refrigeration Table' where you can find online). 2. You need to determine the coefficient of performance based on your answer to the previous question (1). 3. You need to determine the compressors mechanical efficiency.
During an isentropic process of 3 lb/sec of air, the temperature increases from 50 deg F to 290 deg F. Find the work for a nonflow process. -96012 BTU/s -69012 BTU/s O -123.38 BTU/s O -132.38 BTU/s
