Need all questions solved please!

1) You have a window air conditioning unit that operates on a Rankine refrigeration cycle similar to the one in the example in Sandler pp158-162. I talked about this in class on Thursday. Use the cycle with an expansion valve as opposed to the one with a turbine. The evaporator works at 10C and the condenser at 60C. The working fluid is HFC-134a (Freon) - P-H plot is on page 68 of Sandler (also in the files section on Canvas as Figure 3.3-4.pdf) a. Make a table for each step of the cycle. The P and T are the properties of the Freon downstream of the process, and the H,S,Q (dot), and W (dot) are the changes as it goes through the process. Assume 0.01kg/sec for the flow rate of Freon through the system. b. Determine the amount of work needed for each kilojoule of cooling. c. Compare this to the thermodynamic ideal (no entropy generation) of how much work is needed for each kilojoule of cooling when operating between 10 and 60C. d. Why do air-conditioners drip water? This is occurs in one of the steps above - you will also need some common thermodynamic logic. 2) You have CO2 going through a 10cm diameter pipeline at a rate of 10kg/min. The CO2 is at a temperature of 60C and a pressure of 10MPa. Calculate the average velocity of the CO2 in the pipeline. Hint: First find the molar volume of the CO2 using the principle of corresponding states. 3) Estimate the molar volume of propane at T=400K and P=7.5MPa using the principle of corresponding states and the charts in Chapter 6
