Question 7 5 pts The entropy of a system consisting of refrigerant-134a at 24°C is 0.45 kJ/kg-K. The quality of the R- 134a is closest to: 50% Not applicable 25% O 75%
Question 3 (10 points) Find the specific volume of Refrigerant R-134a at 0.9 MPa, and 70 °C using the ideal gas and real gas assumptions. Then determine the percentage error between two values, (greater value-smaller value)/greater value) 100. Round the answer to one significant figure. (The properties of R-134a are given as R = 0.08149 kJ/kg-K, Tcr = 374.2 K, Pcr = 4.059 MPa) 7.5 % 10.6 % 16,5 %

Question 3 Determine the specific volume of refrigerant-134a vapour at 0 9 MPa and 70°C based on, (a) The ideal-gas equation (b) The generalızed compressibility chart, and (c) Data from tables Also, determine the error involved in the first two cases (7) (9) (2) [181 CON
A Refrigeration System Using R-134A In a refrigeration system, the refrigerant R-134A begins as saturated vapor at -15°(State 1). It then goes through a reversible adiabatic compressor to reach State 2. After flowing through the condenser (a heat exchanger), the refrigerant exits as saturated liquid at 70°C (State 3). It is then throttled by going through an expansion valve, to reach State 4. It finishes the cycle by going through another heat exchanger (the evaporator), to return to State 1....
Using the book, write another paragraph or two: write 170 words: Q: Compare the assumptions of physician-centered and collaborative communication. How is the caregiver’s role different in each model? How is the patient’s role different? Answer: Physical-centered communication involves the specialists taking control of the conversation. They decide on the topics of discussion and when to end the process. The patient responds to the issues raised by the caregiver and acts accordingly. On the other hand, Collaborative communication involves a...
